Title: Sialic acid metabolism in the gut microbiota
Dr. Juge has 25-year expertise in the molecular studies of carbohydrate-protein recognition in gut biology and microbiology, and food biotechnology. She is a deputy leader of the Gut Microbes and Health Institute Strategic Programme at the Quadram Institute Bioscience (QIB, Norwich, UK) and an elected fellow of the Royal Society of Biology. Her previous research at Marseille University (France) and Carlsberg Research Institute (Copenhagen, Denmark) focused on the structure-function relationships of plant and microbial carbohydrate-active enzymes and their potential biotechnological application. Since joining QIB in 2007, she has led a Research Group focusing on the Glycobiology of Host-Microbe interactions in the gut. Currently, her group focuses mainly on defining how gut bacteria adapt to the intestinal mucosal environment and the role of mucin glycans in the crosstalk between the gut bacteria and the host. Their work uncovered novel sialic acid metabolism pathways in gut bacteria, contributing to their fitness in the mucus niche and communication with the host. They are also interested in how cell-surface glycosylation of gut symbionts influences the host immune response. Her Lab is involved in initiatives promoting Glycosciences in Europe, such as Sweet Crosstalk or Glytunes multidisciplinary European Training Networks or CarboMet academic-industry network.

Title: From mucin-type O-glycans to bacterial polysaccharides
Inka Brockhausen received her Ph.D. in Biochemistry at the University of Toronto, Canada. At Toronto’s Hospital for Sick Children, she studied both structures and biosynthesis of O-and N-glycans and discovered a number of novel enzymes in the O- and N-glycosylation pathways. As an associate professor at the University of Toronto, her research interest focused on structural and enzymatic glycosylation abnormalities in cancer and cystic fibrosis. Further studies on the link between glycosylation changes in arthritis and inflammatory conditions were carried out at Queen’s University, Kingston, Canada. A major interest became the discovery of novel glycosyltransferases in bacteria, in collaboration with synthetic chemists, e.g., Walter Szarek, Ole Hindsgaul, Vladimir Torgov, and others that were instrumental in the synthesis of natural substrate analogs. Glycosylation inhibitors were developed that could alter the biological properties of cells or could be anti-bacterial compounds. Current directions in the Brockhausen lab at the Department of Biomedical and Molecular Sciences aim to understand polysaccharide synthesis in bacteria and fungi and the mechanisms of enzymes involved in carbohydrate metabolism. Brockhausen also has a keen interest in protein aggregation in neurodegeneration and is a member of the Centre for Neuroscience Studies.

Title: Complex Regulation of domain-specific O-Mannosylation by Three Non-redundant Enzyme Families
Dr. Adnan Halim is a biochemist specializing in mass spectrometry-based glycoproteomics. He obtained his Ph.D. from Gothenburg University, Sweden, in 2012, where he developed methods based on hydrazide chemistry to enrich N- and O-linked glycopeptides from human tissues. This approach led him to discover O-GalNAc linkage to tyrosine residues on amyloid-beta peptides from human cerebrospinal fluid. In 2012, Adnan was recruited to Copenhagen Center for Glycomics (CCG), where he pursued his postdoctoral training and interest in mass spectrometry, protein glycosylations, and precise genome editing. At CCG, Adnan focused on the elusive O-linked mannose modification in eukaryotes. He made major breakthroughs in this field by discovering cadherin/plexin O-mannosylations and the TMTC1-4 glycosyltransferases (GT105). Adnan was promoted to associate professor/group leader at CCG in 2016. Using a combination of techniques, including CRISPR/Cas9 engineering in cell lines and advanced mass spectrometry, his team is currently exploring the functions and regulations of non-classical O-Man glycosylations in mammalian systems.

Title: Cancer immunotherapy targeting glycosphingolipids (GSLs)
Alice L. Yu, MD, PhD, is an Academician of Academia Sinica, Taiwan. She is a Distinguished Chair Professor & Deputy Director of the Institute of Stem Cell & Translational Cancer Research at Chang Gung Memorial Hospital and Professor Emeritus at the University of California in San Diego.
As a pioneer in cancer immunotherapy, Dr. Yu has taken an anti-GD2 monoclonal antibody (Dinutuximab) from preclinical to phase III clinical trial, culminating in its FDA approval for the treatment of high-risk neuroblastoma in 2015. This marks the first immunotherapeutic agent to target glycolipids worldwide. She has continued to improve the efficacy of anti-GD2 immunotherapy through international collaboration. Her group has demonstrated the adverse impact of Globo H expression on the outcome of patients with hepatoma, cholangiocarcinoma, and gallbladder cancer.
