Background
Tumor necrosis factor ligand superfamily member 4(TNFSF4/OX40L) is a single-pass type II membrane protein. OX40L is expressed on the surface of activated B cells,T cells,dendritic cells and endothelial cells. OX40L binds to OX40(CD134),a member of the TNF receptor superfamily that is expressed predominantly on activated CD4+ T cells. OX40-OX40L co-stimulates signal to promote the survival and proliferation of activated CD4+ T cells and prolong the immune response. It involved in T-cell proliferation and cytokine production. Additional,it has been found association with systemic lupus erythematosus,no association with occurrence of atherosclerosis.
