Jose Fernando Maya-Vetencourt
Dr. José Fernando Maya-Vetencourt obtained his Bachellor degree in Biology at the University of the Andes in Merida. Later on he got a MSc degree on Biochemistry and Cellular Biology, in the context of an international research project, at the Ecole Normale Supérieure in Paris. Afterwards, he earned a PhD degree and a Post Doc in Neurobiology at the Scuola Normale Superiore of Pisa while working with Lamberto Maffei. He then moved to the Italian Institute of Technology (IIT), as a Post Doc, in Rovereto. At the moment, he is a Research Scientist at the IIT in Genova working with Fabio Benfenati. In addition to his research activities at the IIT, he obtained the "abilitazione scientifica" and was recently appointed (2015) as Adjunct Professor in the School of Medicine and Pharmacy, at the University of Genova. His research interests centre on (i) neuronal interfaces designed to substitute damaged tissues in the nervous system and (ii) experience-dependent mechanisms of neuronal plasticity that underlie sensory perception and behaviour. Dr. Maya-Vetencourt is author of 4 book chapters, 3 patents, and 22 publications in peer-reviewed journals, including: Science, Nature Neuroscience, Nature Materials, Nature Communications, Journal of Physiology, Frontiers in Systems Neuroscience, European Journal of Neuroscience, Neural Plasticity, Journal of Experimental Neuroscience, Advanced Healthcare Materials, Journal of Alzheimer's Disease. He has delivered more than 20 scientific presentations at international meetings abroad. His academic record includes > 1800 citations with an “H-index” 14 during the last 5 years according to Google Scholar (Impact Factor/Manuscript: 7.84; Total Impact Factor: 132.6). He is member of the Italian Society of Neuroscience (SINS), the American Society of Neuroscience (SfN), and the Italian Physiological Society (SIF). He works as an associate review editor for “Frontiers in Neurogenomics” and “Frontiers in Cellular Neuroscience”. In the year 2017, he was awarded two prestigious and independent scientific recognitions as "Young Investigator": one by the Italian Physiological Society in Pavia and another by the Federation of European Physiological Societies in Vienna.
J.F. Maya-Vetencourt is currently leading the following research projects
• Project 1: Artificial Retina in the RCS retinal degeneration rat model: functional and behavioral recovery of vision in Retinitis pigmentosa
• Project 2: Development of an artificial retinal prosthesis in a swine model of blindness: towards the human phase-1 experimentation
• Project 3: Role of the transcription factor REST on brain plasticity in health and disease as assessed by optogenetics
Summary of Research Projects
• Utilization of neuronal interfaces in retinal pathologies of rodents and swines
Recently, in the department of Synaptic Neuroscience and Technology led by Prof. Benfenati at the IIT, Dr Maya-Vetencourt started to work on an innovative line of research that centres on the development and employment of optoelectronic interfaces as a therapeutic approach to retinal pathologies. After setting-up an in vivo electrophysiology laboratory, Dr. Maya-Vetencourt initiated to study the application of the aforementioned photovoltaic interfaces as neuronal prosthesis in retinal degenerative diseases, such as retinitis pigmentosa and age-related macular degeneration, in both rodents and pigs. The figure shows the 3-layers prosthetic device (upper pannel, dorsal and transversal view) implanted in the subretinal space (lower pannel) of the eye in the rat (Maya-Vetencourt et al. Nat Materials 2017, 16(6): 681). In parallel, we are working with an artificial retina specially designed for the swine eye. We are implanting such photovoltaic device in pigs bearing photoreceptor degeneration, to evaluate the rescue of visual functions and to develop the surgical technique of implantation in an eye that resembles that of humans as the last experimental step before the phase-1 experimentation in man. We are also testing novel polymeric interfaces based on new materials and geometries to develop more advanced, next-generation retinal prostheses. The purpose of the artificial retina project is to promote the development of new therapeutic strategies using animal models of genetic illnesses of the human retina. This translational line of research is clinically relevant in retinal diseases with an incidence of 1 every 4000 people worldwide for which there is currently no medical treatment.
• Mechanisms of neuronal plasticity in the visual system assessed by optogenetics coupled to eletrophysiology
The brain translates information from the external world through signals generated by the electrical activity associated with sensory inputs and orchestrates adaptive responses to changing environmental conditions by processes of neuronal plasticity. Epigenetic modifications of chromatin structure that regulate gene transcription, and therefore plasticity, have recently emerged as a conserved mechanism by which the nervous system translates external information. The master transcriptional repressor REST is a critical regulator of chromatin structure and gene expression, but its precise role in brain physiology and disease is still debated. In this multidisciplinary research project we are addressing the role of the transcriptional repressor REST in processes of visual cortical plasticity in adulthood. This is achieved by employing light-sensitive optogenetic probes that modulate REST activity by illumination with an unprecedented temporal and spatial resolution. The left figure depicts the light-sensitive domain (Avena sativa) that was used for the molecular design of the optogenetic probe previusly created in the laboratory (Paonessa et al. PNAS 2016, 113: E91). The right figure corresponds to the brain of an adult mouse that has been monolaterally infected with the ligh-sensitive probe (GFP labeling) in the primary visual cortex. The identification of epigenetic mechanisms and plasticity genes is an issue of high interest in the field of brain plasticity and repair with potential clinical applications in pathological states where a reorganization of neuronal circuitries may be beneficial in adult life.
