Galectin-1 impacts on glucose homeostasis by modulating pancreatic insulin release.

Type-2 diabetes mellitus (T2DM) is an expanding global health problem, involving defective insulin secretion by pancreatic β-cells and peripheral insulin resistance, leading to impaired glucose regulation. Galectin-1-an endogenous lectin with affinity for N-acetyllactosamine (LacNAc)-containing glycans-has emerged as a regulator of inflammatory and metabolic disorders. However, the role of galectin-1 in glucose homeostasis and pancreatic β-cell function, independently of hypercaloric diets, has not been explored.

Glycosylation-dependent galectin-receptor interactions promote infection.

() constitutes the most prevalent sexually transmitted bacterium worldwide. Chlamydial infections can lead to severe clinical sequelae including pelvic inflammatory disease, ectopic pregnancy, and tubal infertility. As an obligate intracellular pathogen, has evolved multiple strategies to promote adhesion and invasion of host cells, including those involving both bacterial and host glycans.
