背景信息

ICOSLG, also known as B7-H2, CD275 or GL50, is a type I transmembrane glycoprotein belonging to the B7 ligand family. B7-H2/ICOSLG is extensively expressed on professional antigen-presenting cells including B cells, macrophages, and dendritic cells, as well as non-lymphoid cells including mesenchymal stem cells, endothelial cells, fibroblasts, and tumor cells. It is a specific ligand for the T-cell-specific cell surface receptor ICOS and acts as a co-stimulatory molecule. The interaction of B7-H2/ICOSLG and ICOS plays important roles in the activation, proliferation, differentiation, and cytokine production of T cells as well as in the antibody secretion from B cells during secondary immune responses.
