The research activity of Professor De Castro is in carbohydrate structural chemistry, and her training in this subject started during her bachelor thesis, which focused on plant polysaccharides. Since then, even though Professor De Castro continued her work on carbohydrate structural chemistry, she shifted her interests and dedicated her activity to the analysis of the bacterial membrane carbohydrate components, paying attention, but not limiting the work, to Gram-negative bacteria and lipopolysaccharides (LPSs). This work has resulted in the development of state-of-the-art chemical and spectroscopical approaches that have been later applied with success to different kinds of carbohydrates, such as those from the bacteria of the gut microbiota or those from the giant viruses. This last topic is Professor De Castro's major field of research.
Professor De Castro is the author/co-author of about 130 peer-reviewed publications, an associated Editor for the journal Carbohydrate Polymers, and a member of the editorial board of Carbohydrate Research, Glycobiology, and Polysaccharides. She fruitfully collaborates with different research institutions, such as the Department of Plant Pathology (University of Nebraska Lincoln, NE, USA) and the Structural and Genomics Information Laboratory in Marseille (France).
Title: Galectins, Atg8ylation, and Stress Granules in Autophagy and Membrane Stress Response
Dr. Vojo Deretic is the department chair of the Department of Molecular Genetics and Microbiology at the University of New Mexico School of Medicine and the director of the NIH-funded Autophagy, Inflammation and Metabolism (AIM) Center of Biomedical Research Excellence. The AIM center aims to promote autophagy research nationally and internationally and to develop a cadre of junior faculty along with senior experts in this area to study fundamental mechanisms and how autophagy intersects with a broad spectrum of human disease and health states. He received his undergraduate, graduate, and postdoctoral education in Belgrade, Paris, and Chicago. Dr. Deretic’s main contributions to science come from studies by his team on the role of autophagy in infection, immunity, and inflammation. Recently, Dr. Deretic’s group developed the concept of a cellular system termed MERIT for coordinated membrane repair, removal, and replacement. This involves recognition of exposed glycoconjugates on damaged membranes, membrane repair, removal of membranes by autophagy, and replacement of membranous organelles through respective biogenesis programs.
Title: Exploring Glycosylation-dependent Pathways as Modulators of Intestinal Inflammation
Dr. Mariño received her Ph.D. in Chemistry from the University of Buenos Aires. She continued her training as a postdoc at the University of Dundee (Scotland, UK) and later, at the National Institute for Bioprocessing, Research, and Training (Dublin, Ireland), integrating her chemical vision of carbohydrates into the biochemistry of glycans and the structural analysis of glycoconjugates in physiological and pathological contexts. After relocating to Argentina, she established the Functional and Molecular Glycomics Lab (Institute of Biology and Experimental Medicine). As an Independent Researcher at CONICET, she focuses on how inflammatory conditions could alter the glycome in inflammatory bowel diseases and colorectal cancer and whether these changes can promote the establishment of altered lectin-glycan interactions and, in doing so, influence the immune response. Her goal is to capitalize on glycoimmunological mechanisms that could potentially re-wire immune circuits in these pathologies, providing novel opportunities for translational medicine.
Based on her glycoanalytical experience, she also offers consultancies on glycosylation analysis to the Latin American Life Sciences Industry. She received several prizes for her work, including the "Carlos B. Udaondo" award from the National Academy of Medicine (2019). She is the current National Representative for Argentina at the International Glycoconjugate Organization.
