The paper shows that growth factors induce rapid desialylation of cell surface glycoproteins, enabling reversible changes in glycan structure and function through galectin-mediated endocytosis.

This paper develops a synthetic delivery vector for mucosal vaccination that induces mucosal immunity and CD8+ T cell responses in mice.

The paper identifies how spatial N-glycan rearrangements on α5β1 integrin nucleate galectin-3 oligomers, determining endocytic fate and retrograde trafficking.

This study investigates how N-glycosylation sites on SLC3A2 evolve and regulate amino acid transport and redox balance, revealing their role in cellular trafficking and bird evolution.

The paper investigates retrograde and anterograde transport of LAT-vesicles during immunological synapse formation, identifying specific proteins regulating each pathway.
