Nanoprobes and Nanoswitches

About

Research in the laboratory focuses on developing nanoscale tools to study biological systems. These tools include instrumentation based on proximity probes, such as electrochemical tunnelling microscopy and spectroscopy and single molecule force spectroscopy, that we apply to investigate electron transfer in individual redox proteins, and other biophysical and biochemical interactions.

These studies are relevant to understand lipid membrane dynamics, to the development of biosensors and molecular electronics devices, and have led to the discovery of long-distance electrochemically gated electron transport between partner proteins of the respiratory and photosynthetic chains.

Another set of nanotools that we are developing is based on engineered molecular actuators that can be switched with light, such as azobenzene, which can be chemically attached to biomolecules in order to remotely control their activity (photopharmacology). They include peptide inhibitors of protein-protein interactions, small molecule enzymatic inhibitors, and photoswitchable ligands of a diversity of other proteins.

Among several applications, these compounds have enabled photoactivated chemotherapy, photocontrol of cellular signaling mediated by ion channels and G protein-coupled receptors, photocontrol of cardiac activity and locomotion, sensory restoration, and photocontrol of brain waves.

Based on these tools, we have also developed two-photon pharmacology to manipulate and study the activity of neurons and glia in intact brain tissue with pharmacological selectivity and sub-cellular three-dimensional resolution.

IBEC’s research group “Nanoprobes and nanoswitches” creates a system based on light to inhibit the endocytocis and control its spatio-temporal dynamics. The newly developed light-sensitive small-molecule inhibitors of endocytosis (called dynazos) are water-soluble, cell permeable, photostable, and enable fast photoswitchable inhibition of endocytosis. This technology will allow more accurate and controlled studies were endocytosis is crucial, as in cellular grow, differentiation and motility.

IBEC researchers develop new multi-responsive molecules able to self-assemble in water forming fiber-like structures. The so-called discotic molecules show responsiveness to temperature, light, pH, and ionic strength and they might show great potential for medical applications such as drug delivery systems, diagnosis or tissue engineering. Edgar Fuentes is a PhD student in the Nanoscopy for Nanomedicine Group led by Lorenzo Albertazzi at the Institute for Bioengineering of Catalonia (IBEC). Within this group, Edgar and his colleagues focus on the synthesis of novel smart supramolecular materials for drug delivery.

Rossella Castagna a postdoctoral researcher in the Nanoprobes and Nanowitches group at IBEC was awared with the ISOP2019 prize last week 9th International Symposium on Photochromism held in Paris. This recognition comes from her contribution to the field of photochromism and for the results that were collectively obtained in their group in the field of photopharmacology. Rossella presented the group results on photoswitchable drugs at the reference international meeting for photochromism, held every 3 years, where she was awarded with the conference prize. According to the organizing committee, such a prize rewards the most talented young researchers whose contribution is expected to notably impact the field of photochromism.

José Antonio del Río, Pau Gorostiza, and Samuel Sánchez have been awarded in two of the “la Caixa” calls. José Antonio del Río, principal investigator of the Molecular and Cellular Neurobiotechnology Group at IBEC, is one of the winners of the second edition of the call for applications in biomedicine and health. Del Río’s project focuses on analysing the molecular mechanisms involved in the genesis and propagation of tau protein in brain cells. This protein is linked with several neurodegenerative processes and is present in numerous diseases such as Alzheimer’s. Pau Gorostiza, principal investigator of the Nanoprobes and Nanoswitches Group, also received an award at the second edition of the call for applications for research projects in biomedicine and health. In this case, for his project on degenerative eye conditions such as retinitis pigmentosa, which causes blindness due to the progressive degeneration of the cones and rods, which are the light sensitive cells.

Scientists from the Institute for Bioengineering of Catalonia develop a technique that enables them to work out the specific function of a neuronal receptor according to its location in the brain. The study, published in PNAS, is based on the activation of photoswitchable drugs with micrometric precision and offers new opportunities in neurobiology. Schizophrenia, depression, myasthenia… Many neurological diseases are due to the malfunctioning of a neuronal receptor. These proteins, also known as neuroreceptors, are responsible for sending and detecting neurotransmitters, chemical substances that allow communication between neurons.
