SUMMARY:IBEC Seminar: Miguel Holgado
DESCRIPTION:Technologies for highly multiplexed in-vitro diagnostic systems and organ on chips. Cases studies for COVID-19 and neurodegenerative diseases\nMiguel Holgado\, Centro de Tecnología Biomédica-Universidad Politécnica de Madrid and Instituto de Investigación Sanitaria del Hospital Clínico San Carlos \nTechnologies for biomarkers screening are of very high importance\, particularly when they are reliable\, cost effective\, easy to use for measuring multiples biomarkers in a single diagnostic KIT working with real biological samples such as serum\, saliva\, wastewater or culture medium. In this paper we report technologies for the development of a highly multiplexed kit for detecting biomarkers of COVID19 in serum\, saliva[1] and wastewater analyzing their correlation with the severity of the COVID19 and showing relevant figures about the severity (90 patients in serum)\, immunity (200 volunteers in saliva donating sample every 10 days in three months)\, and wastewater. This technology has also demonstrated for measuring particular proteins of the SARS-COV-2 in wastewater\, which results have been compared with Polymerase Chain Reaction. Recently we are using these technologies for detecting Alzheimer Disease (AD) biomarkers in serum. \nIn concrete\, we have achieved to detect the total tau protein at the level of 10 pg mL-1 in serum as a biomarker for early detection of the AD[2]. Other biomarkers are also under development right now. In this term\, the use of advanced in vitro diagnostic systems with organ-on-chip based technologies are of a high relevance because can be used for monitoring relevant biomarkers secreted by the cells\, tissues or biopsies in these types of bioreactors. We have recently developed microfluidic chips acting as bioreactors for neuronal circuits on a chip for biological network monitoring[3] and brain slice-on-a-chip for organotypic culture and effective fluorescence injection testing[4]. Cultured neuronal networks (CNNs) are a robust model to closely investigate neuronal circuits’ formation and monitor their structural properties evolution. Typically\, neurons are cultured in plastic plates or\, more recently\, in microfluidic platforms with potentially a wide variety of neuroscience applications. As a biological protocol\, cell culture integration with a microfluidic system provides benefits such as accurate control of cell seeding area\, culture medium renewal\, or lower exposure to contamination. In this paper it is presented a novel neuronal network on a chip device\, including a chamber\, fabricated from PDMS\, vinyl and glass connected to a microfluidic platform to perfuse the continuous flow of culture medium. \nAs a step forward\, we employ this technology as an alternative brain slice-on-a-chip\, integrating an injection system inside the chip to dispense a fluorescent dye for long-term monitoring. Hippocampal slices are cultured inside these chips\, observing fluorescence signals from living cells\, maintaining the cytoarchitecture of the slices. Having fluorescence images of biological samples inside the chip demonstrates the effectiveness of the staining process using the injection method avoiding leaks or biological contamination.

SUMMARY:PhD Discussions: Sefora Conti
DESCRIPTION:Mechanical phenotyping of colorectal cancer patient derived organoids based on LGR5 expression\n\n\n\nSefora Conti\, Integrative cell and tissue dynamics group \n\n\n\nColorectal cancer (CRC) tumors are composed by heterogeneous cell populations comprising differentiated cells and a small pool of cancer stem cells (CSCs). The link between cancer cell differentiation states and their metastatic potential has been the focus of extensive investigation\, with some studies pointing to microenvironmentally defined plasticity as a mechanism indispensable for metastasis formation. Another aspect that might be determinant in tumor cells ability to successfully disseminate\, intravasate\, survive in the blood stream\, extravasate\, colonize distant organs and form secondary tumors is their mechanical phenotype. \n\n\n\nAdopting a bottom-up approach\, we performed a broad biophysical characterization of CRC patient derived organoids (PDOs)\, engineered to fluorescently label cells expressing LGR5\, a well-established marker for CSCs. We show that CRC cells differentiation states are associated with distinct biomechanical phenotypes\, with potential repercussions on their metastatic ability. \n\n\n\nAt the single cell level\, LGR5+ cells display a more elongated and polarized shape while the LGR5- cells exhibit higher roundness and a smaller asymmetry in the stress field. LGR5+ are stiffer compared to their differentiated counterparts and more prone to adopt a fast amoeboid-like migration under confinement.  At the molecular level\, cancer stemness is related to differential expression of the ERM protein family\, responsible of tethering the cell membrane to the underlying actin cortex. \n\n\n\nThese distinct mechanical phenotypes translate to different migratory and morphological phenotypes at a cluster level. Clusters expressing high levels of LGR5 showed a more spread and flattened shape compared to more differentiated clusters. Moreover\, LGR5 expression in clusters is negatively correlated with their migration speed and their polarization state. Hence\, clusters containing more differentiated cells migrate faster\, display higher roundness and higher polarization state. \n\n\n\nAt higher complexity levels\, such as interactions with endothelial cells\, LGR5 expression in CRC clusters affects their ability to adhere to an endothelial monolayer and form a gap through which they attach to the underlying collagen coating. Notably\, we found that clusters expressing more LGR5 have an advantage while attaching to the endothelium as indicated by higher attachment rate and shorter time to form a gap. \n\n\n\nBased on these findings relating distinct mechanical phenotypes to LGR5 expression\, we speculate that mechanical adaptability coupled with cancer plasticity may be an indispensable mechanism for cancer progression.

SUMMARY:Open BIST Seminar: Dr. Wiktor Szymanski
DESCRIPTION:Molecular basis for the use of light in medicine\nWiktor Szymanski\, Medical Imaging Center\, University Medical Center Groningen \nLight is a unique control element in chemistry and biology\, because it can be safely delivered with very high precision to modulate processes in space and time. In this educational lecture\, aimed at Master students but hopefully of interest to all academics\, I will discuss the main processes that a molecule can undergo once it has been promoted to the excited state under light irradiation. Using the Jablonski diagram as the starting point\, I will outline how these processes are or could be used in the clinic for diagnostics (optical and optoacoustic imaging) and therapy (photodynamic therapy and photopharmacology). \n\nWiktor Szymanski received his PhD degree from The Warsaw University of Technology\, Poland\, in 2008\, working under the supervision of Prof. Ryszard Ostaszewski. He spent two years working on the use of biotransformations in organic chemistry with Prof. Ben L. Feringa and Prof. Dick B. Janssen at the University of Groningen. Since 2010 he has been working on the construction of photoactive protein- peptide- and DNA-bioconjugates and photopharmacology in the Feringa Labs. In 2014\, he joined the Medical Imaging Center\, University Medical Center Groningen\, where he was appointed in 2015 as tenure track assistant professor and in 2019 as associate professor (adjunct hoogleraar).

SUMMARY:PhD Discussions: Sefora Conti
DESCRIPTION:Mechanical phenotyping of colorectal cancer patient derived organoids based on LGR5 expression\nSefora Conti\, Integrative cell and tissue dynamics group \nColorectal cancer (CRC) tumors are composed by heterogeneous cell populations comprising differentiated cells and a small pool of cancer stem cells (CSCs). The link between cancer cell differentiation states and their metastatic potential has been the focus of extensive investigation\, with some studies pointing to microenvironmentally defined plasticity as a mechanism indispensable for metastasis formation. Another aspect that might be determinant in tumor cells ability to successfully disseminate\, intravasate\, survive in the blood stream\, extravasate\, colonize distant organs and form secondary tumors is their mechanical phenotype. \nAdopting a bottom-up approach\, we performed a broad biophysical characterization of CRC patient derived organoids (PDOs)\, engineered to fluorescently label cells expressing LGR5\, a well-established marker for CSCs. We show that CRC cells differentiation states are associated with distinct biomechanical phenotypes\, with potential repercussions on their metastatic ability. \nAt the single cell level\, LGR5+ cells display a more elongated and polarized shape while the LGR5- cells exhibit higher roundness and a smaller asymmetry in the stress field. LGR5+ are stiffer compared to their differentiated counterparts and more prone to adopt a fast amoeboid-like migration under confinement.  At the molecular level\, cancer stemness is related to differential expression of the ERM protein family\, responsible of tethering the cell membrane to the underlying actin cortex. \nThese distinct mechanical phenotypes translate to different migratory and morphological phenotypes at a cluster level. Clusters expressing high levels of LGR5 showed a more spread and flattened shape compared to more differentiated clusters. Moreover\, LGR5 expression in clusters is negatively correlated with their migration speed and their polarization state. Hence\, clusters containing more differentiated cells migrate faster\, display higher roundness and higher polarization state. \nAt higher complexity levels\, such as interactions with endothelial cells\, LGR5 expression in CRC clusters affects their ability to adhere to an endothelial monolayer and form a gap through which they attach to the underlying collagen coating. Notably\, we found that clusters expressing more LGR5 have an advantage while attaching to the endothelium as indicated by higher attachment rate and shorter time to form a gap. \nBased on these findings relating distinct mechanical phenotypes to LGR5 expression\, we speculate that mechanical adaptability coupled with cancer plasticity may be an indispensable mechanism for cancer progression.

SUMMARY:IBEC Seminar: Iris Batalha
DESCRIPTION:Nanotherapeutics – ‘How we sometimes underestimate the influence of little things’\nIris L. Batalha\, Institute for Bioengineering of Catalonia (IBEC) \nDeaths caused by infections from antibiotic-resistant bacteria are expected to skyrocket over the next decades\, with a staggering 10 million deaths per year projected for 2050. Treating infections by intracellular pathogens\, such as M. tuberculosis\, is ‘a perfect storm’. The WHO revealed that while some 50 new antibiotics and 10 biologics are under development\, only half of those target WHO-priority pathogens and the majority have very limited benefits when compared to existing antibiotics. Reformulating existent drugs in nanocarriers may help achieving enhanced efficacy and safety while reducing dose frequency\, by providing temporal and localised control of drug exposure. In this talk\, I will present my work on the synthesis of dual-drug tunable nanoparticle-based antibiotics\, which showed increased bacterial killing efficacy in a zebrafish larval model of mycobacterial infection when compared to free drugs at the same concentration. In addition\, nanoparticles were able to efficiently penetrate mycobacterial cords and granulomatous lesions – shielded regions of difficult access by free drugs\, improving the therapeutic effect. \n\nIris Batalha is currently a Junior Leader Research Fellow at the Institute for Bioengineering of Catalonia (IBEC) in Barcelona\, a Panel Tutor in Nanotherapeutics at the University of Cambridge Institute of Continuing Education\, a freelance Senior Innovation Consultant at Inspiralia (Spain and USA)\, a Co-founder\, Director and Editor-in-Chief of the non-profit organisation Women Ahead of Their Time (WATT)\, and a Research Associate at Peterhouse College.

SUMMARY:IBEC Seminar: Iris Batalha
DESCRIPTION:Nanotherapeutics – ‘How we sometimes underestimate the influence of little things’\nIris L. Batalha\, Institute for Bioengineering of Catalonia (IBEC) \nDeaths caused by infections from antibiotic-resistant bacteria are expected to skyrocket over the next decades\, with a staggering 10 million deaths per year projected for 2050. Treating infections by intracellular pathogens\, such as M. tuberculosis\, is ‘a perfect storm’. The WHO revealed that while some 50 new antibiotics and 10 biologics are under development\, only half of those target WHO-priority pathogens and the majority have very limited benefits when compared to existing antibiotics. Reformulating existent drugs in nanocarriers may help achieving enhanced efficacy and safety while reducing dose frequency\, by providing temporal and localised control of drug exposure. In this talk\, I will present my work on the synthesis of dual-drug tunable nanoparticle-based antibiotics\, which showed increased bacterial killing efficacy in a zebrafish larval model of mycobacterial infection when compared to free drugs at the same concentration. In addition\, nanoparticles were able to efficiently penetrate mycobacterial cords and granulomatous lesions – shielded regions of difficult access by free drugs\, improving the therapeutic effect. \n\nIris Batalha is currently a Junior Leader Research Fellow at the Institute for Bioengineering of Catalonia (IBEC) in Barcelona\, a Panel Tutor in Nanotherapeutics at the University of Cambridge Institute of Continuing Education\, a freelance Senior Innovation Consultant at Inspiralia (Spain and USA)\, a Co-founder\, Director and Editor-in-Chief of the non-profit organisation Women Ahead of Their Time (WATT)\, and a Research Associate at Peterhouse College. From 2017 to 2020\, she was a joint Research Associate at the Department of Engineering Nanoscience Centre and Department of Medicine Molecular Immunity Unit\, University of Cambridge. From 2014 to 2017\, she worked at the Department of Chemical Engineering and Biotechnology\, University of Cambridge\, and the biopharmaceutical company MedImmune/Astrazeneca\, followed by a brief experience as a healthcare/pharmaceutical consultant. Her research interests and expertise lie in medical and pharmaceutical research and development\, particularly in the fields of nanobiotechnology\, bio-inspired materials\, downstream processing\, formulation and drug delivery. \n  \nSala Baobab\, Tower I\, 11 Floor\, IBEC

SUMMARY:PhD Discussions: Srivatsava Viswanadha Venkata Naga Sai and Madhura Murar
DESCRIPTION:Mechanical characterization of murine pluripotency dissolution\nSrivatsava Viswanadha Venkata Naga Sai\, Cellular and Molecular Mechanobiology Group \nMouse Embryonic Stem Cells (mESCs) can be maintained in ground/naïve state when grown in a defined N2B27 media with the supplementation of two inhibitors (2i) for MEK/Erk and GSK3β. Upon 2i withdrawal\, mESCs exit naïve state and become functionally mature\, acquiring differentiation competence. From a mechanical point of view\, the instruction for initiating ground state exit is the integrin mediated mechano-sensing of extra cellular matrix (ECM). Although laminin has been found to be the pivotal ECM ligand for pluripotency dissolution\, the down-stream mechano-responses accompanying its sensing\, their spatio-temporal evolution and\, their regulatory role in mESC maturation remain unclear. In this work\, we combine mechanical measurements\, functional characterization\, and live cell imaging to unravel the role of mESCs-ECM interactions during naïve state exit and pluripotency dissolution. We employ a Rex1::GFPd2 expressing mESC line to monitor naïve state exit in real time\, combined with a laminin-rich ECM environment. During naïve state exit\, we observe a progressive increase in cell-ECM interaction\, marked by an increase in traction forces\, growth of focal adhesions\, and the reorganization of the basal actin from a mesh-like network into an oriented filamentous morphology reminiscent of stress fibres. Furthermore\, inhibition of non-muscle myosin-II using blebbistatin significantly delayed naïve state exit\, suggesting a regulatory role of cell contractility in mESC maturation. We finally investigate the role of these changes in cell-ECM interactions in mediating nuclear mechanoresponses\, and their influence in mESC pluripotency dissolution. \n\n\nDual peptide-mediated design of polymeric nanoparticles: towards precision prostate cancer targeting\nMadhura Murar\, Nanoscopy for Nanomedicine Group \nA key bottleneck of current cancer treatments is the lack of selective targeting of cancer cells to reduce undesirable side-effects. Nanoparticles (NPs) allow for the design of ligand-coated materials that can fulfil this function but have not yet shown consistent clinical results to make the ‘magic bullet’ theory a paradigm. The inconsistencies may be due to a range of biological factors like differences in disease models or expression levels of target receptor(s). NP design parameters could play a key role in alleviating these inconsistencies and significantly influence the therapeutic efficacy. To further improve this efficacy\, multi-ligand targeting strategies have been proposed\, however\, they remain controversial as they involve an intricate interplay between multitude of factors such as choice of ligands\, their receptor binding affinities\, NP surface densities\, stoichiometric ratios etc.\, thereby calling for a thorough understanding of the impact of these properties to improve their targeting potential. \nWithin this context\, we employ two cell targeting peptides (WQP and GE11) having different binding affinities to PSMA and EGFR receptors\, which are known PCa biomarkers. We evaluate the effect of multivalency of low affinity WQP peptide over its monomeric form on PSMA targeting. We find that by increasing the valency of WQP on NP surface\, we observe a higher cellular uptake of WQP-NPs over the monomeric form\, attributing to a stronger avidity. Next\, we assess the effect of two conjugation strategies using the high affinity GE11 peptide and study their impact on EGFR targeting in a systematic manner. We observe that conjugating GE11 peptide to PLGA-PEG polymer prior to NP formulation (pre-conjugation) allows for a higher and more controlled GE11 content on NP surface than conjugating it to formulated PLGA-PEG NPs (post-conjugation)\, consequently leading to a higher cellular uptake. \nBased on these findings\, we report a synthetic strategy for dual peptide-NPs with systematically varied properties\, specifically surface valencies and ratios\, and establish their impact on selective targeting in a prostate cancer (PCa) model. First\, we study the impact of peptide valencies on NP surface of dual NPs in comparison to single peptide-NPs on the selective cellular uptake in different PCa cell lines. Once we establish optimal surface valency\, we check the effect of different surface peptide ratios on cellular uptake and determine the optimal ratio for enhanced targeting of only those cells over-expressing both receptors\, by the virtue of improved selectivity. Somewhat counterintuitively\, we observe an increase in tumor cell uptake of NPs with lower peptide density\, which can be attributed to improved surface distribution of the peptide\, allowing for an enhanced availability to react with target receptor. This increase in uptake is a result of the two peptides acting in co-operation\, as opposed to simply an additive effect. Our findings demonstrate that through refined design and well-characterized NP formulations\, dual-peptide targeted nanosystems hold potential to provide precise cancer treatments. \n  \nThis PhD Discussion session will be held at Tower I\, 11th floor Baobab room\, at 10:00am.
