Description

B7-H5 (B7 homolog 5), also known as platelet receptor Gi24, C10orf54, Dies1, VISTA, PD-1H and SISP1, is a single-pass type I transmembrane glycoprotein that belongs to the B7 family of the Ig superfamily. Unlike other B7 family members that usually contain one Ig V-like and one Ig C-like domain in the extracellular region, mature B7-H5 has only one Ig V- like domain. B7-H5 is expressed in bone, on embryonic stem cells (ESCs), and on tumor cell surfaces. On ESCs, it interacts with BMP-4 and potentiates BMP signaling and the transition from an undifferentiated to a differentiated state. On tumor cells, B7-H5 both promotes MT1-MMP expression and activity and serves as a substrate for MT1-MMP. This increases the potential for cell motility. B7-H5 can be shed by MT1­MMP, generating a soluble 30 kDa extracellular fragment and a 25-30 kDa membrane-bound fragment. B7-H5 is expressed on the surface of naïve CD4+ T cells and regulatory T cells. Its expression is up­regulated in vivo on activated monocytes and dendritic cells. It is reported that B7-H5 inhibits CD4+ and CD8+ T cell proliferation, and their production of IL­2 and IFN­γ. Its expression on tumor cells attenuates the anti­tumor immune response and enables more rapid tumor progression. In contrast, it has also been reported that B7-H5 limits disease progression in the autoimmune disease model EAE.
