SUMMARY:IBEC Seminar: Magali Suzanne
DESCRIPTION:Mechanical impact of cell delamination on tissue dynamics\, in developmental and tumoral contexts\nCentre de Biologie Intégrative\, CNRS/UMR 5088\, Université Toulouse III\, Toulouse\, France \nHow mechanical forces drive morphogenesis is a fundamental question in the field of biomechanics. Combining imaging\, genetics\, biophysical and modeling approaches\, we found that apoptotic cells\, far from being eliminated passively\, exert a force before dying and thus actively participate in tissue remodeling. This transient force\, generated in the depth of the epithelium\, constitute a mechanical signal involved in tissue folding. Comparing apoptotic cell dynamics to cells undergoing EMT\, we found that a very similar apico-basal force is generated at the onset of EMT.\nWe further deciphered how these forces are transmitted at the tissue scale through the characterization of a specific mechanical state favoring directional force transmission and developed a new method that offers the opportunity to extract automatically\, in strongly deformed epithelia\, a precise characterization of the spatial organization of a given cytoskeletal network combined to morphological quantifications in highly remodeled 3D epithelial tissues.\nIn parallel\, we turned to cancer mechanics\, focusing particularly in tumor progression. Cancer is a largely widespread pathology that corresponds to an overproliferation of cells that could finally invade others tissues. Tumors develop through three increasingly aggressive steps: (1) hyperplasia\, which corresponds to cells overproliferation; (2) dysplasia\, during which cells can acquire a more mesenchymal phenotype\, and finally (3) metastasis. Tumor development can be influenced by mutations but also by external factors\, such as extracellular matrix rigidity. However\, a comprehensive understanding of the intrinsic factors driving tumor evolution is still lacking. Our recent unpublished work identifies unexpected factors that could influence tumor development\, and more specifically the hyperplasia/dysplasia transition\, a critical step in tumor aggressiveness. This work highlights puzzling differences between developmental and tumoral mechanics.

SUMMARY:IBEC Seminar: Theodore Alexandrov
DESCRIPTION:Spatial single-cell metabolomics reveals metabolic cell states\nEMBL \nRecent discoveries put metabolism into the spotlight. Metabolism not only fuels cells but also plays key roles in health and disease. In parallel\, emerging single-cell technologies opened a new world of cell types and states previously hidden beneath population averages. Yet\, methods for discovering links between metabolism\, cell states\, metabolic plasticity and reprogramming on the single-cell level and in situ are crucially lacking. Our research aims to contribute bridging this gap. First\, we will present how the emerging technology of imaging mass spectrometry can be used for the spatial profiling of metabolites\, lipids\, and drugs in tissues. These efforts are enabled by our big data community cloud platform METASPACE which is increasingly used across the world. Next\, we will present method SpaceM for spatial single-cell metabolomics. SpaceM detects 100+ metabolites or 500+ lipids from thousands of individual cells together with fluorescence and morpho-spatial features. We used SpaceM to characterize how stimulating human hepatocytes with fatty acids led to the emergence of two co-existing subpopulations outlined by distinct cellular metabolic states. Inducing inflammation with the cytokine IL-17A perturbs the balance of these states in a process dependent on NF-κB signalling. We will show how a high-throughput version of the SpaceM method helps discover and characterize metabolic states of activated CD4+ T cells from peripheral human blood. Finally\, we will present how spatial multi-omics can reveal the relationships between cell types and cell states in tissues. Overall\, such methods can open novel avenues for understanding metabolism in tissues and cell cultures on the single-cell level.

SUMMARY:IBEC Seminar: Loris Rizzello
DESCRIPTION:Towards an evolutionary-driven universal therapy against (intracellular) pathogens\nUniversità degli Studi di Milano \nWe are living a time where we believe antibiotics are the cornerstone of any infectious disease-based therapy. It is definitely out of question that antibiotics saved millions of people worldwide in the last century\, and that they are still doing it very efficiently. Nevertheless\, their extensive abuse\, especially for zoonic applications\, contributed to the rise of antibiotic resistance (AMR). AMR is one of the biggest threats in the current human history because it is estimated that the majority of the antibiotics\, currently used in the clinics\, will be completely ineffective for the eradication of infectious disease. This has been defined as “The New Dark Ages of Antibiotics”\, which is expected to start in the next decades if no actions will be taken now. There are several causes behind AMR\, but one of the most relevant is the exposure of bacteria to sub-lethal doses of the antimicrobials. One of the big aim of our research efforts is to design of a new generation of therapy that counteract this issue. It is inspired on solutions already provided by Nature\, and it is based on the strategy exploited by a specific class of viruses that infect and kill bacteria only\, called as bacteriophages\, which are completely safe and unharmful to humans. The development of a new therapy possessing the requirements to avoid the rise in AMR represents a new legacy for the future generation in terms of anitibacterial therapies\, exaclty in the same way antibiotics changed the human history in the 20th century.

SUMMARY:IBEC Seminar: Zev Gartner
DESCRIPTION:Building tissues to understand how tissues build themselves\nZev Gartner\, UCSF \nCells assemble into tissues and organs through an active process termed self-organization. Harnessing tissue self-organization will ultimately advance applications as diverse as disease modeling and regenerative medicine\, while revealing new strategies for fighting disease. However\, progress towards these applications is limited by our incomplete understanding of how the properties of tissues emerge from their cellular building blocks.  I will discuss two recent projects that aim to address this knowledge gap.  In a first project\, we use human mammary organoids to make the remarkable observation that tissues can behave as dynamic structural ensembles. We model the ensemble using a maximum entropy framework\, and demonstrate the probability distribution of tissue structures is a function of the entropy associated with cell arrangements\, the energy associated with cell interfaces\, and mechanical fluctuations associated with cell motility.  We map these parameters back to measurable molecular and mechanical properties of cells and their microenvironment\, allowing us to engineer the structural ensemble quantitatively and systematically.  In a second project we use the morphogenesis of mouse intestinal villi to reveal that tuning the geometry and active mechanics of the epithelial/mesenchymal interface is sufficient to sculpt a diversity of tissue forms. In the gut\, MMP and Myosin-II dependent fluidization of a contractile and adhesive sub-epithelial mesenchyme results in a dynamic monolayer of cells with a high surface tension. Minimization of surface energy results in a process we call “mesenchymal de-wetting\,”  which results in the formation of an array of multicellular condensates that act to pattern and fold the overlying epithelium. Manipulating the properties of the cells or the interface results in predictable changes to the pattern and shape of the folds. These studies have some important implications for tissue engineering\, disease progression\, and our understanding of tissue self-organization in other contexts.

SUMMARY:IBEC-IFIBYNE Webinar Cycle (online) 12th July 2023 at 16:00 Javier Ramon
DESCRIPTION:Organ on a chip models to emulate multi systemic metabolic diseases\nJavier Ramon\, IBEC \nExisting on-chip tissue models typically represent a single organ\, limiting systemic drug investigations. Microscale tissue analog systems aim to improve drug and toxicity predictions across various organs. However\, multi-organ devices are limited\, and none have explored skeletal muscle and pancreatic islets. We developed a novel multi-organ-on-a-chip platform for real-time\, sensitive monitoring of cross-talk between two organs. Unlike previous electrochemical platforms\, our sensing system offers cost-effectiveness\, label-free detection\, easy integration\, multiplexing\, and real-time monitoring. This platform quantifies secreted proteins with high sensitivity\, crucial for understanding the relationship between skeletal muscle and the pancreas. Our work shows promise for disease modeling\, drug screening\, and personalized medicine. \n\nDoctor Javier Ramon is an ICREA Professor since 2021 and the leader of the Biosensors for Bioengineering group at the Institute of Bioengineering of Catalonia. Javier studied Chemistry at the University of Catalonia and completed his PhD at the CSIC in the Institute of Advanced Chemistry of Catalonia. He conducted his postdoctoral research in Japan at the Advanced Institute of Materials and returned to Spain in 2016 as a Ramon y Cajal researcher. His research is focused on tissue engineering\, biomaterials\, biosensors\, and integrating these technologies into organ-on-chip devices to study diseases and drug screening.

SUMMARY:IBEC Seminar: Dan Vigneron
DESCRIPTION:Translation and Initial Patient and Volunteer Studies with Hyperpolarized Carbon-13 MR Molecular Imaging\nDan Vigneron\, Department of Radiology & Biomedical Imaging\, University of California San Francisco \n“Hyperpolarized (HP) carbon-13 MRI is an emerging molecular imaging method to monitor enzymatic conversions through key\, previously-inaccessible biochemical pathways. Over 1000 human HP carbon-13 MR studies to date have shown outstanding research and potential clinical value. Just as MRI has shown value for medical imaging providing information beyond CT/X-ray\, HP C-13 MRI can provide new isotope imaging biomarker information in addition to what PET & SPECT do. HP C13 MRI is safe\, ~2min\, non-radioactive addition to standard-of-care MRI exams\, at costs less than separate PET exam. At the UCSF Hyperpolarized MRI Technology Resource Center\, we are developing new techniques for rapid dynamic acquisitions to measure HP conversion rates for [1-13C]pyruvate to [1-13C]lactate\, [1-13C]alanine and 13C-bicarbonate in the abdomen\, pelvis\, heart and brain to monitor cellular metabolism in normal tissues and pathologies. We are conducting over 15 clinical trials of HP C-13 MRI and have translated 4 different HP probes into first human studies: [1-13C]pyruvate\, [2-13C]pyruvate\, [1-13C]alpha-ketoglutarate\, and 13C-urea. Initial results demonstrate the ability to detect cancer aggressiveness\, response to therapy\, cardiac disease and brain bioenergetics. \n\nDr. Daniel B. Vigneron Ph.D. is a Professor in the Department of Radiology & Biomedical Imaging and at the University of California\, San Francisco. He also has joint appointments in the Departments of Bioengineering & Therapeutic Sciences and Neurological Surgery at UCSF and is a member of the UCB/UCSF Bioengineering graduate group. He directs the UCSF Human Imaging Core and the Advanced Imaging Technologies Resource Group that facilitates imaging technique development in the Department of Radiology & Biomedical Imaging including: Hyperpolarized Carbon-13\, PET-MR\, and 7T MR. He also is the Director of the NIH NIBIB-funded Hyperpolarized C-13 MRI Technology Resource Center at UCSF that was recently renewed till 2027 with 20 external collaborative and service projects. This UCSF Hyperpolarized MRI Technology Resource Center also sponsors numerous training and education opportunities including symposia/workshops focused on the development and dissemination of new HP-MRI techniques. Dr. Vigneron was elected Fellow of the International Society of Magnetic Resonance in Medicine in 2009 and to the College of Fellows of the American Institute for Medical and Biological Engineering in 2007. He received the Academy of Radiology Research Distinguished Investigator Award in 2013 and with colleagues was awarded the Gold Medal of the World Molecular Imaging Society in 2014. \nDr. Vigneron obtained his BA in Chemistry from Wesleyan University in Middletown\, Connecticut in 1983\, and he completed his PhD research in Pharmaceutical Chemistry from UCSF in 1988 and then conducted post-doctoral research at the Fox Chase Cancer Center in Philadelphia and at UCSF developing new MRI techniques for characterizing disease and therapy response. Prof. Vigneron’s research is focused on the development of metabolic MRI techniques for research and clinical assessments of human diseases. This research has been reported in over 350 total publications resulting in over 39\,000 citations with an h-index of 109 and an i10-index of 339 and has been funded by 25 NIH grant awards including as PI: 3 P41\, 1 P01 2 U01\, 18 R01 and 1 S10 grant awards. Also\, he has served as the Primary Mentor on 6 NIH career mentored awards. Dr. Vigneron leads the technical development aspects of the hyperpolarized carbon-13 MR program at UCSF and is the Principal Investigator of seven current NIH funded projects focused on new HP metabolic MRI techniques applied to clinical research studies of prostate cancer\, metastatic cancers\, brain disorders and CNS tumors.

SUMMARY:IBEC Seminar: MDr Joanna Sierpowska
DESCRIPTION:Awake brain surgery mapping – a way to mitigate postsurgical impairments and a door to understanding human cognition\nMDr Joanna Sierpowska from the Department of Cognition\, Development and Educational Psychology\, Institute of Neurosciences\, University of Barcelona \nBrain mapping for language and cognition during awake brain surgeries helps neurosurgeons to mitigate postsurgical impairments. At the same time\, it uncovers the truth about brain functional organization. While the cortical procedures are very well studied and widely implemented since the ’50 of the XX century confirming the classical models of language production\, the work on mapping the white matter pathways has developed very recently. The dual pathway model for language introduces the importance of the perisylvian white matter in the processing of speech sounds and word meaning. In the present talk\, I will explain if the model was successfully confirmed by intraoperative language testing. Furthermore\, I will explain how we assess language function associated with the model perioperatively in a large sample of brain tumor patients.

SUMMARY:IBEC Seminar: Virgil Percec
DESCRIPTION:Reprogramming the Factory of Life to Target the Delivery of mRNA via Helical Chirality\nVirgil Percec\, Roy & Diana Vagelos Laboratories\, Department of Chemistry\, University of Pennsylvania\, Philadelphia \nHomochiral helical self-organizations are known at the macroscopic level in nature\, art\, architecture and science for thousands of years [1a\,b]. However\, molecular helicity was discovered in proteins and DNA [2] only in the early 1950th and in molecular\, macromolecular and supramolecular complex nanosystems emerged soon after [1c\,d\,e\,f]. Our ability to program functions at the supramolecular level based on helical chirality is less advanced than the same process at the macroscopic level during Archimedes and Leonardo da Vinci times. The principles “discover-elucidate mechanism-predict programmed primary structure” elaborated in our laboratory and aided by synthetic methodologies developed also in our laboratory for accelerated modular-orthogonal synthesis of programmed structures such us Ni-catalyzed cross-coupling\, mixed-ligand\, thio-bromo click\, SET-organic and polymerizarion reactions\, self-accelerated and self-interrupted synthesis including selected examples of homochiral helical self-organizations and functions together with the molecular factory of life will be briefly explained. The origins of helical homochirality is equivalent to the origins of life although the origins and the rational of biological membranes homochirality continues to be debated [3]. Inspiration from amphiphilic Janus dendrimers [4a] and Janus glycodendrimers [4b] discovered in our laboratory allowed to transit from the commercial viral and four-component lipid nanoparticle synthetic vectors for delivery of mRNA to the one-component ionizable multifunctional sequence-defined amphiphilic Janus dendrimers (IAJDs) delivery vector [5]. The current status of the molecular design principles providing the least expensive and the simplest access to targeted delivery of mRNA with programmed IAJDs will be discussed in great details. Targeted delivery of mRNA to all organs is expected to change the field of nanomedicine at the most fundamental level by providing unprecedented avenues to new vaccines and therapeutics. \nReferences \n\n(a) Percec\, V.; Xiao\, Q.

SUMMARY:IBEC Seminar: Dr. Andy Tay
DESCRIPTION:Biomaterials for cancer study and accelerate wound healing\nDr. Andy Tay \, Assistant Professor\, Presidential Young Professor\, Department of Biomedical Engineering \nMagnetic hydrogels are materials containing magnetic microparticles which help transduce magnetic fields into mechanical forces. In the presence of a static magnet\, the stiffness of magnetic hydrogels can be altered to investigate the reversible effects of matrix softening and stiffening on cellular behaviours. Here\, I will describe how we exploit this unique feature of our material for cancer study. \nThe World Health Organization estimates that 10% of the world’s population suffers from diabetes\, and diabetic patients has a 15-25% lifetime risk of getting diabetic foot ulcers.

SUMMARY:IBEC Seminar: Simone Reber
DESCRIPTION:Conserved nucleocytoplasmic density homeostasis drives cellular organization across eukaryotes\nSimone Reber\, Max Planck Institut for Infection Biology\, Berlin (invited by Pere Roca-Cusachs) \nThe packing and confinement of macromolecules in the cytoplasm and nucleoplasm has profound implications for cellular biochemistry. How intracellular density distributions vary and affect cellular physiology remains largely unknown. We show that the nucleus is less dense than the cytoplasm and that living systems establish and maintain a constant density ratio between these compartments. Using label-free biophotonics and theory\, we show that nuclear density is set by a pressure balance across the nuclear envelope in vitro\, in vivo and during early development. Nuclear transport establishes a specific nuclear proteome that exerts a colloid osmotic pressure\, which\, assisted by entropic chromatin pressure\, draws water into the nucleus. Using C. elegans\, we show that while nuclear-to-cytoplasmic (N/C) volume ratios change during early development\, the N/C density ratio is robustly maintained. We propose that the maintenance of a constant N/C density ratio is the biophysical driver of one of the oldest tenets of cell biology: the N/C volume ratio. In summary\, this study reveals a previously unidentified homeostatic coupling of macromolecular densities that drives cellular organization.

SUMMARY:IBEC Seminar: Jaap den Toonder
DESCRIPTION:Microfluidic technology enabling biomedical applications\nJaap den Toonder\, Microsystems Research Section\, Department of Mechanical Engineering\, and Institute for Complex Molecular Systems\, Eindhoven University of Technology.  \nCurrently\, visiting professor at IBEC\, Barcelona \nMicrofluidics is the science and technology of manipulating and analyzing fluid flow at small scales\, typically from millimeters down to micrometers. At these scales\, fluid flow is almost always laminar which enables excellent control over the flow. Microfluidic devices can be made using a range of microfabrication approaches and materials\, and these enable to integrate tailored electronic or mechanical functions. These unique properties of microfluidic technologies\, and the ongoing further development of the technology\, enable a range of new biomedical applications\, including diagnostic and monitoring devices\, medical implants\, and organ-on-chip. \nIn this lecture\, I will present recent developments within three research lines of our lab. (1) Bio-inspired microfluidics: A novel microfluidic flow generation concept inspired by nature\, which is based on magnetic nano- and micro-actuators we call “artificial cilia”; integrated in microfluidic devices\, these can be used to induce flow\, to manipulate particles\, and as actuators in cellular mechano-transduction research. (2) Microfluidic devices for health: Examples of microfluidic devices for health applications\, specifically a sweat sensing device for non-invasive semi-continuous monitoring of hospitalized patients\, and a smart eye implant to control eye pressure in glaucoma patients after surgery. (3) Organ-on-chip: A game-changing technology in which human cells are cultured in microfluidic chips simulating and predicting the response of healthy and diseased human tissues. I will focus on cancer-on-chip approaches to understand initial stages of cancer metastasis\, and on our lumen-based organ-on-chip models that are enabled by a 3D sugar printing technique we developed.

SUMMARY:IBEC Seminar: Josep Puigmartí-Luis
DESCRIPTION:What can microfluidic technologies offer during self-assembly processes?\nJosep Puigmartí-Luis\, Departament de Ciència dels Materials i Química Física\, Institut de Química Teòrica i Computacional (invited by César Rodriguez-Emmenegger) \nSelf-assembly has long being used to control covalent and non-covalent interactions where molecular design has been the major driving force to achieve a desired outcome. Like in nature\, a full control over self-assembly processes could lead to rationalized structure-property correlations\, a long-time sought in chemistry\, physics and materials science. However\, the pathways followed and the mechanisms underlying the formation of supramolecular aggregates are still a major challenge for the scientific community. Accordingly\, the elucidation of nucleation and growth mechanisms will be highly required to push supramolecular chemistry to the next level\, where access to nature inspired functions will be accomplished. In this contribution\, I will present how reaction-diffusion (RD) conditions established within microfluidic devices can be used to uncover pathway complexity as well as to trigger pathway selection. Specifically\, I will show that microfluidic RD conditions provide an unprecedented kinetic control over self-assembly processes; for example\, enabling the isolation of well-defined kinetically trapped states as well as unprecedented metastable intermediates. This research provides a new tool to study and understand supramolecular chemistry\, and opens up new avenues for the engineering of advanced functional assemblies and systems. \n\nProf. Dr. Josep Puigmartí-Luis is a chemist who completed a master in Chemistry and Food Engineering at “Institut Químico de Serrià (IQS)” (2003) and did a PhD in materials science at Institut de Ciència de Materials de Barcelona (ICMAB). His work in supramolecular and flow chemistry\, has been awarded with “Premi Antoni de Martí i Franquès de Ciències Químiques”\, award from the Institut d’Estudis Catalans (2009)\, St. Jordi award from the Institut d’Estudis Catalans and the Societat Catalana de Química (2006) and an ETH fellowship in 2008. \nIn 2012\, he was appointed a Ramon Y Cajal (RyC) researcher\, but after two years as a RyC\, he decided to move back to Switzerland where in 2015 was awarded an ERC starting grant to study and control self-assembly processes of metal-organic based crystalline materials. In 2019\, he was appointed as an ICREA professor and since August 2020 his group is located at the University of Barcelona (UB).

SUMMARY:IBEC Seminar: Martí Duocastella
DESCRIPTION:Toward the next generation of 3D optical microscopes: faster\, deeper\, and label-free\nMartí Duocastella\, Departament de Fisica Aplicada\, Universitat de Barcelona \nThree-dimensional (3D) optical microscopy is the tool of choice for characterizing the structure and dynamics of biological systems at sub-cellular resolution. However\, most microscope architectures are tailored to capture two-dimensional (2D) information from moderately thin samples labeled with fluorophores. Due to constraints posed by light scattering and the requirement for mechanical focus translation\, existing systems provide shallow penetration depth and low volumetric imaging speed\, thus falling short of unraveling biological complexity inside medium-sized organisms or even organoids. In this talk\, I will discuss our efforts to overcome these issues and achieve sub-millisecond imaging at potentially millimeter depths and without labels. Our strategy consists of focusing\, modulating\, and guiding light by exploiting the acousto-optic effect\, that is\, ultrasound-induced refractive index gradients. The unique interaction between ultrasound and light enables rapid 3D light control\, making it suitable for the development of inertia-free light sheet microscopes that lack mechanically moving parts and offer imaging rates of tens of volumes per second. It also facilitates illumination encoding in single-pixel cameras\, enabling scanless 2D imaging at 5 kHz. Interestingly\, applying ultrasonic waves in a scattering medium acts as an instantaneous waveguide embedded in the medium\, helping to redirect light toward a 7-fold deeper focus. I will discuss the advantages and pitfalls of these acousto-optic technologies and illustrate them with applications\, including imaging of spheroids and flowing samples. \n\nMartí Duocastella is a Serra Hunter full professor in the Department of Applied Physics at Universitat de Barcelona (UB) and leader of the Dynamic Optical Systems Lab. He completed his PhD in Physics at UB in 2010 and then moved to Princeton University as a postdoctoral research associate\, where he also became the vice-president of Research and Development of the startup company TAG Optics. In 2014 he joined Istituto Italiano di Tecnologia as a researcher (group leader)\, until returning to Barcelona as a faculty member in 2019. His research focuses on novel optical methods for three-dimensional (3D) light engineering\, with applications in materials science\, sensing\, and biology. He is an ERC Consolidator Grant awardee. \nIn 2012\, he was appointed a Ramon Y Cajal (RyC) researcher\, but after two years as a RyC\, he decided to move back to Switzerland where in 2015 was awarded an ERC starting grant to study and control self-assembly processes of metal-organic based crystalline materials.

SUMMARY:IBEC Seminar: Dr. Neil Lin
DESCRIPTION:Epithelial Cell Variability is Governed by Physics Principles and Has Mechanobiology Impacts\nDr. Neil Lin\,  Assistant Professor of Mechanical Engineering and Bioengineering at University of California\, Los Angeles (UCLA). \nBiological systems inherently exhibit variability\, seen in diverse cell shapes\, sizes\, and mechanical properties. Despite its prevalence\, our understanding of the role of phenotypic heterogeneity in cell biology is incomplete. This talk explores how basic physics governs cell-to-cell variability in epithelial monolayers and its impact on biological processes. The first part covers how cell shape heterogeneity influences chromatin organization during crowding. The second part demonstrates that in deformed epithelial layers\, nucleo-cytoskeleton coupling regulates intracellular strain distribution\, influencing cellular mechanoresponse and gene expression. Overall\, cell-cell variability significantly shapes tissue development and remodeling. \n\nDr. Neil Lin is an Assistant Professor of Mechanical Engineering and Bioengineering at University of California\, Los Angeles (UCLA). He obtained his Ph.D. in physics at Cornell University\, studying the microscopic mechanisms that underlie the non-Newtonian suspension flow property. From there\, he went on to do a postdoctoral fellowship at Harvard University\, studying approaches to recreate microenvironment cues for recapitulating kidney functions in vitro. He joined UCLA in 2019\, and his research is to utilize mechanobiology principles to engineer epithelial tissues. His honors include an NIH MIRA\, Prostate Cancer Foundation Young Investigator Award\, and BMES CMBE Rising Star Award.

SUMMARY:IBEC Seminar: Pavan Kumar Bosukonda
DESCRIPTION:Smart artificial microcompartments: motility and communication\nPavan Kumar Bosukonda\, Assistant Professor at the Department of Chemistry\, Indian Institute of Technology Roorkee \n  \nNature is a continuous source of inspiration for the design of smart and intelligent materials. In particular\, cells which are the building blocks of life display a complex symphony of various chemical/physical processes which make “life” possible and give it the characteristics which enable life to flourish and sustain. The topology of control systems in place within living cells offer many lessons in design of smart artificial microcompartments or microbots. In this talk\, I will be discussing examples of microcompartments which are capable of smart adaptive motility\, self-assembly and chemical-mediated communication with each other. We use simple buoyancy forces to regulate movement of our microcapsules and use antagonistic control to design relatively complex autonomous behavior by employing stratified chemical environments. The motile microcapsules can turn on/off chemical reactions and carry out logistics of molecular cargo. Also\, I will discuss how we can use the combination of a stimuli responsive hydrogel and stratified environments to design a chemo-mechanical oscillator.  Another focus will be our results on multiphase coacervates and how they formulate a pathway for self-assembly of microdroplets into clusters or tissue-like structures and trigger chemical communication between them. \n\nBrief Bio: Dr. Pavan Kumar Bosukonda is an Assistant Professor at the Department of Chemistry\, Indian Institute of Technology Roorkee. He carried out his doctoral studies at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR)\, Bangalore\, in the field of porous materials wherein his specific interest was to use supramolecular strategies for pore engineering in mesoporous silica. After completing his Ph.D. in 2015\, he moved to the University of Bristol\, UK\, to work with Prof. Stephen Mann as a Marie-Sklodowska-Curie Postdoctoral Fellow in the field of protocells. His current research interests are focused on developing strategies to fabricate motile microcompartments\, study of multiphase dynamics in liquid-liquid phase separation and designing strategies for regulating chemical communication between microcompartments.

SUMMARY:IBEC Seminar: Prof. Aitor Aguirre
DESCRIPTION:Reverse engineering human heart  development with pluripotent stem cells\nProf. Aitor Aguirre\, Institute for Quantitative Health Science and Engineering (IQ) and the Department of Biomedical Engineering at Michigan State University  \nDuring development\, an exquisitely orchestrated series of biological processes lay down the map for the entirety of our bodies and carry it out to perfection. However\, occasional errors occur (due to mutations\, environmental factors\, and other causes) and lead to congenital defects\, the most common birth defect in humans affecting 1% of all newborns. Certain conditions such as obesity\, diabetes\, infections or drug use can increase this risk much further.\nTo tackle CHDs\, we are reverse engineering human heart development on a dish with the use of pluripotent stem cells\, creating heart organoids or synthetic mini-hearts. By recapitulating  aspects of heart development in vitro\, under fully controlled conditions\, we can dissect gene networks and morphological changes that give rise to specific parts of the heart to understand and prevent CHD\, such as single ventricle defects. Furthermore\, we can also use these mini-hearts as models to study the exposure to environmental conditions and other factors that are very poorly known. \n\nDr. Aguirre obtained his B.S. in Biology and M.S. in Biochemistry and Molecular Biology at the University of the Basque Country and his Ph.D. in Material Science at the Institute for Bioengineering of Catalonia (IBEC). For his postdoctoral training Dr. Aguirre joined The Salk Institute under the supervision of J.C. Izpisua-Belmonte\, where he explored in vivo reprogramming applied to cardiac regeneration\, making significant contributions to non-coding RNA biology in human cardiac development (Cell Stem Cell\, 2014; Circulation\, 2015). Dr. Aguirre became Assistant Professor of Medicine at the University of California\, San Diego in 2017 and joined the Institute for Quantitative Health Science and Engineering (IQ) and the Department of Biomedical Engineering at Michigan State University one year later. He became associate professor in 2023 and is currently the Chief of IQ’s Developmental and Stem Cell Biology Division and the Director of MSU’s Stem Cell Core Facility. Dr. Aguirre has extensive experience in cardiac development\, cardiovascular disease\, tissue engineering and -omic approaches. Dr. Aguirre has received numerous awards and nominations including the Hispanic Center of Excellence award at the University of California\, a career development NHLBI K01 award and frequently serves in grant review panels for the NIH and European Commission\, among others.

SUMMARY:IBEC Seminar: Al Jord
DESCRIPTION:Mechanisms of Organelle Remodeling for Cellular Function\nAl Jord\, Group leader of Mechanisc of organelle remodeling group\, Centre for Genomic Regulation\, Barcelona \nTo function\, organisms rely on vital organs which\, in turn\, rely on specialized cells. At the subcellular scale\, cell specialization is notably driven by robust mechanisms of organelle remodeling. Thus\, discovering these mechanisms is key for the fundamental understanding of organisms in health and disease\, as well as for improved organ engineering. In this seminar\, I will discuss my research on organelle remodeling in somatic and female germ cells. I will first show how multiciliated cells – critical for nervous\, respiratory and reproductive organs – repurpose conserved mechanisms of cell division to remodel organelles for motile ciliogenesis. I will then talk about how oocytes deploy a biophysical mechanism\, based on cytoplasmic force tuning\, to mechanically remodel nuclear RNA-processing organelles for reproductive success. I will conclude with some future research plans\, blending my past and present interests into an interdisciplinary project that will venture into unexplored grounds of nuclear organelle mechano-regulation in somatic cells to deepen our understanding of organ development and homeostasis. \n\nKey relevant publications : \n  \nAl Jord\, A. et al.

SUMMARY:IBEC Seminar: Ernesto Mejías
DESCRIPTION:Vaccinia in & as next-gen oncolytic virotherapy: exploiting the synergy between oncolysis and chemotherapy\nDr Ernesto Mejías Pérez Ramón y Cajal researcher Instituto Maimonides de Investigación Biomédica de Córdoba (IMIBIC)\, Universidad de Córdoba. Dpto. de Biología Celular\, Fisiología e Inmunología \nIn the fight against cancer\, conventional treatments fall short of healthcare expectations. Oncolytic virotherapy is a versatile and robust alternative. With exceptional immunogenic features\, Vaccinia virus (VACV) is a standout oncolytic vector whose anti-tumor ability is usually enhanced by gene deletions for better safety and heterologous genes insertions for improved cytotoxicity. Yet\, VACV’s translation to effective anti-tumor treatments suffers from major shortcomings that warrant immediate solutions\, among those the limited efficacy as a standalone treatment need to be overcome. \nTo tackle this challenge head-on\, my laboratory is focused on developing next-generation synergistic therapeutic strategies towards strengthening the anti-tumor effects of the oncolytic virotherapy based on Vaccinia virus by boosting the infection efficacy and triggering a strong chemosensitization upon nucleoside analog treatment. This approach builds on the unique multifaceted role that SAMHD1 has at the interface oncolysis:chemotherapy.

Cell Biology\, Neurobiology and Biophysics department\, Utrecht University\, The Netherlands \nAbscission is the last step of cell division leading to the complete separation of the two sister cells and consists in the cutting of a cytoplasmic bridge. Abscission is mediated by the membrane remodelling machinery ESCRT which also triggers the severing of a thick bundle of microtubules that needs to be cleared prior to abscission. Here\, we use mouse embryonic stem cells\, which transition from slow to fast abscission during exit from naïve pluripotency to investigate the molecular mechanism for abscission dynamics. We identify a feedback loop between the activity of Aurora B\, mechanics\, and microtubule stability as a main regulator of abscission speed.

SUMMARY:IBEC Seminar: Emilio Parisini
DESCRIPTION:Engineering enzymes for biomedical and biotechnological applications\nEmilio Parisini\, Latvian Institute of Organic Synthesis (Riga\, Latvia)\, University of Bologna (Italy) \nEnzyme engineering has the potential to improve the activity\, the stability and the substrate recognition of enzymes. As such\, it paves the way for the design of novel enzymes with improved performances for a wide range of applications. This rational approach can accelerate the production and the use of biocatalysts in different biotechnological sectors\, thus in turn allowing the improvement of chemical processes through the application of green chemistry concepts.  In this talk\, two examples from our current research will be discussed: \nFructosyl Peptide Oxidases (FPOX) are deglycating enzymes that find application as key enzymatic components in diabetes monitoring devices. Indeed\, their use with blood samples can provide a measurement of the concentration of glycated hemoglobin and glycated albumin\, two well-known diabetes markers. However\, the FPOX currently employed in enzymatic assays cannot directly detect whole glycated proteins\, making it necessary to perform a preliminary proteolytic treatment of the target protein to generate small glycated peptides that can act as viable substrates for the enzyme. This is a costly and time consuming step. The rapidly growing demand for cheap\, efficient and rapid diabetes monitoring tests could be met by developing enzymatic assays for glycated hemoglobin and albumin that do not require a preliminary digestion of the proteins. In our lab\, we used an in silico protein engineering approach to enhance the overall thermal stability of the enzyme and widen it active site to improve its catalytic activity toward large substrates. \nThe fast and uncontrolled accumulation of plastic waste in the environment has long begun to impact on the natural ecosystems and to pose an existential threat to all forms of life on our planet. Advanced technical solutions to the plastic waste management problem are therefore in urgent demand. To this end\, enzymatic approaches to plastic degradation hold great promises as novel and more efficient enzymes are constantly being developed. Leaf-branch Compost Cutinase (LCC)\, a naturally occurring PETase\, has been reported to outperform all other known PET-degrading enzymes and to present a melting temperature (Tm) of 84.7°C. This enzyme has been noticeably engineered in 2020\, leading to the so-called ICCG variant (Tm = 94.0°C)\, the current gold standard. In our lab\, we engineered a LCC that features significantly enhanced PETase activity and thermal stability relative to the gold standard ICCG.

SUMMARY:IBEC Seminar: Kevin Braeckmans
DESCRIPTION:Delivering effector molecules in cells in vitro and ex vivo by photoporation.\nKevin Braeckmans\, Biophotonics Research Group\, Lab. General Biochemistry and Physical Pharmacy\, Ghent University\, Belgium \nDelivery of bioactive compounds\, such as proteins and nucleic acids\, into cells in vitro or ex vivo is a generic requirement for many applications in the life sciences\, such as for the engineering of therapeutic cells. Physical delivery methods are attractive in this context as they are well-controlled\, and can accommodate a broad variety of effector molecules and cell types. Photoporation is such a recently developed physical delivery technology which combines laser stimulation with photothermal nanoparticles. Localized thermal effects upon laser irradiation can create pores in the cell membrane\, allowing the influx of external molecules in cells. Importantly\, photoporation is very gentle to cells\, resulting in excellent cell viability and preservation of a cell’s phenotype and functionality. In this presentation I will give an overview of the most notable work that we performed on photoporation as a next-generation transfection technology in the past decade. \n\nKevin Braeckmans first studied physics before doing his doctoral studies in pharmaceutical sciences at Ghent University in Belgium. From early on he was passionate about developing biophotonics technologies for drug delivery and diagnostics. In 2008 he was appointed professor at Ghent University as the group leader of the Bio-Photonics Research Group. In 2015 he received a prestigious ERC Consolidator Grant and became full professor in 2018. His research presently focuses on studying biological barriers to nanomedicines by advanced microscopy techniques\, and combining light with nanoparticles to enable light-triggered drug delivery and related therapeutic applications. He is a co-author of >250 publications\, Clarivate Highly Cited Author in 2022 and 2023\, and co-inventor of 17 patent applications. Presently he is a co-founder and CSO/CTO of the spin-off company Trince.

SUMMARY:IBEC Seminar: Ovijit Chaudhuri
DESCRIPTION:Cell migration and morphogenesis in viscoelastic matrices\nOvijit Chaudhuri\, University of Standford \nThe extracellular matrix (ECM) is a complex assembly of structural proteins that provides physical support and biochemical signaling to cells in tissues. Over the last two decades\, studies have revealed the important role that ECM elasticity plays in regulating a variety of biological processes in cells\, including stem cell differentiation and cancer progression. However\, tissues and ECM are often viscoelastic\, displaying stress relaxation over time in response to a deformation\, and viscoplastic\, exhibiting irreversible deformations in response to mechanical stress.  In this talk\, I will discuss our recent findings on how matrix viscoelasticity regulates various biological processes\, including collective invasion by cancer cells\, morphogenesis of pluripotent stem cells\, and monocyte migration.

SUMMARY:IBEC Seminar: Aurora Hernandez-Machado
DESCRIPTION:Biomicrofluidic analysis of hematological diseases by means of mathematical biomechanical models and statistical analysis: Cells and hydrogels in microchannels and microrheometers\nAurora Hernandez-Machado\, Departament de Fisica de la Materia Condensada\, Universitat de Barcelona \nWe have developed microfluidic devices for precise characterization of hematological diseases. By means of one drop of blood and mathematical models based on biomechanics\, we analyze the properties of cells and microrheological properties such as the viscosity of blood. We will present a microrheometer to determine in a fast\, chip and sensitive way the viscosity of a drop of blood. Experimental results of malaria infected red blood cells in microchannels with endothelial slits and hydrogels with organ-on-a-chip will be discussed. Sprouting is a fundamental cellular behavior that plays an essential role in vascular development and angiogenesis. Due to its relevance to many aspects of human health\, the ability to accurately reproduce cell sprouting is of broad and multidisciplinary interest. We will present microfluidic experiments and compare with theoretical models in which endothelial cells chemotactically migrate into a fibrin-based porous hydrogel which mimics the extracellular matrix. By means of statistical analysis we improve the diagnosis of the hematological diseases. We predict if a sample of blood corresponds to healthy blood or to blood with a hematological disease. We have obtained different performance for the different methods\, some of them with very good results and an accuracy of 94%.

SUMMARY:IBEC Seminar: Nicolò Accanto
DESCRIPTION:2P-BRAINSCOPY: pushing the boundaries of two-photon microscopy to study large neuronal networks in behaving mice.\nNicolò Accanto\, Inserm researcher at the in Insitut de la Vision (IDV)\, in the group of Valentina Emiliani\, Paris  \nIn the past 15 years\, the synergy of two-photon (2P) microscopy and optogenetics has transformed neuroscience\, enabling high-resolution imaging and precise photostimulation of neuronal activity. Today\, understanding how neuronal networks in the brain interact to generate perception\, memory and behaviour\, or in other words\, deciphering the neuronal code\, requires to push the limits of 2P microscopy. \nThis involves studying the brain of freely moving animals engaged in natural tasks and accessing thousands of neurons on a very fast (100 ms) timescale\, across large (> 5 mm) brain regions\, while keeping individual neuron (5 µm) spatial resolutions. \n  \nIn this presentation I will outline our recent endeavours towards these goals. I will first show how 2P holographic photostimulation based on spatial light modulators is capable to precisely target individual neurons within a large volume [1]. I will then describe how we can use minimally invasive GRIN lenses to access deeper brain regions [2]\, below the scattering limit. Finally\, I will detail our most advanced technique: a novel fiber-based miniaturized microscope to image and photostimulate neuronal activity in freely moving mice [3\,4]. In the last part of the talk\, I will present future directions for further developments and applications in neuroscience. \n  \nReferences \n[1] Accanto\, N. et al.
