Title: Mucin Glycans in the Regulation of Microbial Virulence
Professor Ribbeck obtained her Bachelor’s degree and her Ph.D. in Biology from the University of Heidelberg, Germany. She continued her postdoctoral research at the European Molecular Biology Laboratory, Heidelberg, Germany, and the Department of Systems Biology, Harvard Medical School. Professor Ribbeck established her independent research group as a Bauer Fellow at the FAS Center for Systems Biology, Harvard University, in 2007 and joined the Department of Biological Engineering at MIT as an Assistant Professor in 2010.
Her laboratory studies the basic mechanisms of biological hydrogels by which mucus barriers exclude, or allow passage of different molecules and pathogens, and the mechanisms pathogens have evolved to penetrate mucus barriers. It hopes to provide the foundation for a theoretical framework that captures general principles governing selectivity in mucus, and likely other biological hydrogels such as the extracellular matrix, and bacterial biofilms. Her Lab’s work may also be the basis for the reconstitution of synthetic gels that mimic the basic selective properties of biological gels.
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).
Professor Tadashi Suzuki received his Ph.D. (1997) from Department of Biochemistry and Biophysics at University of Tokyo, Japan. He demonstrated the activity and characterized the enzymatic properties of the cytoplasmic peptide:N-glycanase (PNGase/Ngly1) mammalian cells and proposed that this enzyme may be involved in the quality control of newly synthesized glycoproteins. Dr. Suzuki was a postdoctoral fellow at Department of Biochemistry and Cell Biology, State University of New York at Stony Brook (1997-2000). He was an Assistant Professor at University of Tokyo (2002-2004) and a Visiting Associate Professor at Osaka University Graduate School of Medicine (2004-2007). During this period, he identified two cytoplasmic glycosidases, endo-beta-N-acetylglucosaminidase (ENGase) and alpha-mannosidase (Man2C1), involved in the catabolism of free glycans released by the cytoplasmic PNGase. He was a Team Leader at Glycometabolome Team, Systems Glycobiology Research Group, RIKEN. He currently serves as a Chief Scientist at Glycometabolic Biochemistry Laboratory, RIKEN Cluster for Pioneering Research.
His current research interests are (1) clarification of the novel catabolic pathway for glycans on glycoproteins; (2) characterization of biological functions of cytoplasmic peptide:N-glycanase (Ngly1) for the non-lysosomal catabolic pathway of N-glycans; (3) development of new analytical methods for glycans; and (4) development of therapeutics for NGLY1-deficiency.
Title: Targeting Cancer-Associated Sialylation for Cancer Immunotherapy
Dr. Heinz Läubli received his M.D. and Ph.D. at the Institute of Physiology, University of Zürich (Switzerland). He is now an Assistant Professor and a Research group leader at the University of Basel and an Attending physician in the Division of Oncology, and Head of Glycobiology Research in the Department of Biomedicine, at the University Hospital Basel. Dr. Heinz’s research interests are to improve immunotherapy for cancer patients by using translational in vitro and in vivo tumor models, performing correlative analysis of patients treated with immunotherapy, and conducting early clinical interventional trials. His group has been studying the interaction between siaologlycans and their interaction with Siglec receptors on immune cells. It has demonstrated that this pathway can be targeted to augment T-cell stimulation and tumor control. His research goals also include the improvement of cancer immunotherapy by modifying glycans in the tumor microenvironment and glycans of cellular products for adoptive cell therapies, including genetically modified T cells.
Title: Quantitative descriptions of structure-function relationships of glycoSHIELD of coronavirus spike proteins
Dr. Danny Hsu is a Research Fellow at the Institute of Biological Chemistry, Academia Sinica. During his doctorate study at Utrecht University, the Netherlands, he determined the atomic structure of a lantibiotic, nisin, in complex with Gram-positive bacterial cell wall precursor, Lipid II. He coined the term "pyrophosphate case" to explain how nisin targets Lipid II to achieve its antimicrobial activity, providing a blueprint for future antibiotics developments. During his postdoctoral research at the University of Cambridge, UK, Danny demonstrated the proof of concept of using solution-state NMR spectroscopy to investigate the co-translational folding of nascent polypeptide chains on the ribosome. His earlier independent research focused on the folding mechanisms and functional implications of topologically knotted proteins. He currently focuses on developing an integrated biophysics and structural biology platform, including cryo-electron microscopy, mass spectrometry, and molecular modeling, to investigate the structure-activity relationship (SAR) of glycoproteins, and coronavirus spike proteins, in particular, and how mutations impact on the SAR in the context of glycosylation.
Professor Yasuhiro Kajihara received his Ph.D. from the Tokyo Institute of Technology in 1993. He spent two years at the Life Science Research Laboratory of Japan Tobacco Inc. as a postdoctoral fellow. In 1995 he joined Yokohama City University as an assistant professor and was then promoted to associate professor in 2001 and full professor in 2007. At YCU, he developed synthetic methods for oligosaccharides and glycoproteins. In 2009, he moved to the Department of Chemistry at Osaka University. He studies new synthetic methods of glycoproteins in order to understand how oligosaccharides regulate protein functions.

Title: New Insights about the Glycan Ligands of Siglecs and their Ability to Control Immune Cells
The primary focus of Dr. Matthew Macauley’s laboratory is the immunomodulatory sialic acid-binding Siglec family of receptors. His group develops innovative approaches to probe Siglec-glycan interactions on cells and tissues and use new insights about the biological ligands of Siglecs to test hypotheses about the roles of Siglecs in controlling immune cell function.
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.
