Product Detail	T cell activation by APCs is positively and negatively regulated by members of the B7 family. We have identified a previously unknown function for B7 familyrelated protein V-set and Ig domaincontaining 4 (VSIG4). Administration to mice of soluble VSIG4-Ig fusion molecules reduced the induction of T cell responses in vivo and inhibited the production of Th celldependent IgG responses. Unlike that of B7 family members, surface expression of VSIG4 was restricted to resting tissue macrophages and absent upon activation by LPS or in autoimmune inflammatory foci. 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. Function: Phagocytic receptor, strong negative regulator of T-cell proliferation and IL2 production. Potent inhibitor of the alternative complement pathway convertases. Subcellular Location: Membrane; Single-pass type I membrane protein (Probable). Tissue Specificity: Abundantly expressed in several fetal tissues. In adult tissues, highest expression in lung and placenta. Expressed in resting macrophages. Similarity: Contains 2 Ig-like (immunoglobulin-like) domains.
