VSIG4蛋白背景綜述

VSIG4 ( V-set and immunoglobulin domain containing 4 ), also known as complement receptor of the immunoglobulin superfamily (CRIg) and Z39Ig, is a type I  transmembrane glycoprotein. It is a B7 family-related protein and an Ig superfamily member. In contrast to the B7 family members which contain two IgG domains, VSIG4 contains one complete V-type I g domain and a truncated C-type I g domain. VSIG4 is abundantly expressed in several fetal tissues. In ***** tissues, the highest expression of VSIG4 is in lung and placenta. It is also expressed in resting macrophages.No VSIG4 expression appears to be present in T and B cells. The specific expression of VSIG4 on resting macrophages in tissue suggests that this inhibitory ligand may be important for the maintenance of T cell unresponsiveness in healthy tissues. VSIG4 functions as a negative regulator of T cell activation, and may be involved in the maintenance of peripheral T cell tolerance, and is also identified as a potent suppressor of established inflammation. VSIG4 is a phagocytic receptor, strong negative regulator of T-cell proliferation and IL2 production. It is a potent inhibitor of the alternative complement pathway convertases.
