Abstract:
V set and Ig domain containing 4 (VSIG4), a co-inhibitory molecule expressed by macrophages, is a B7 family-related protein. It can serve as the second signal of T cell activation and regulate the function of T cells. It has been found that VSIG4 is essential in maintaining immune tolerance. Moreover, VSIG4 can also act as a complement receptor, playing a role in recognizing pathogens, regulating the complement alternative pathway and inhibiting inflammatory response. This review summarized the expression of VSIG4 and its role in the immune system.
