Abstract

The B7-H family of immune checkpoint molecules is a crucial component of the immune regulatory network for tumors, offering new opportunities to modulate the tumor microenvironment (TME). The B7-H family - which includes B7-H2 (inducible T cell costimulatory ligand, ICOSL), B7-H3, B7-H4, B7-H5 (V-domain immunoglobulin suppressor of T cell activation, VISTA), B7-H6, and B7-H7 (HHLA2) - is known for its diverse roles in regulating innate and adaptive immunity. These molecules can exhibit co-stimulatory or co-inhibitory effects on T cells, influencing processes such as T cell activation, differentiation, and effector functions, and they are involved in the recruitment and polarization of various immune cells. This review explores the structural characteristics, receptor-ligand interactions, and signaling pathways associated with each B7-H family member. We also discuss the family's impact on tumor immunity and potential therapeutic strategies.
