Descripción
V-set and immunoglobulin domain containing 4 (VSIG4) is a complement receptor and immune checkpoint protein that primarily functions as an inhibitory molecule in macrophages and antigen-presenting cells. As a negative regulator of T-cell activation, VSIG4 suppresses immune responses by binding to complement components, thereby reducing inflammation and preventing tissue damage in autoimmune and inflammatory conditions. Its immune-inhibitory properties make VSIG4 a potential target for immune modulation therapies, particularly in autoimmune diseases and cancer immunotherapy. In the tumor microenvironment, VSIG4 expression on macrophages is associated with immune evasion, as it inhibits T-cell-mediated anti-tumor responses. Elevated VSIG4 levels have been linked to poor prognosis in several cancers, including hepatocellular carcinoma and melanoma. Beyond its role in immunity, VSIG4 is implicated in metabolic processes, as it interacts with lipid metabolism pathways in macrophages, influencing foam cell formation in atherosclerosis. Therapeutic strategies targeting VSIG4 are being explored to enhance anti-tumor immunity or regulate excessive inflammation, highlighting its significance as a multifunctional immune regulatory molecule.
