Identification of Galectin-9 (Gal-9) as a B7-H4 binding partner and characterization of their glycosylation-dependent interaction that modulates T cell signaling within a multi-ligand/receptor network
B7-H4, a member of the B7 family, is broadly expressed on various cancer cells and has been implicated in negative immune regulation, particularly in suppressing anti-tumor immunity. However, its receptor and the mechanisms underlying its immunosuppression remain poorly understood. Here, we identify Galectin-9 (Gal-9)...
