Ett höljeglykoprotein och differentieringsantigen som uttrycks på ytan av T-celler. Det binder till CD40 (CD40 antigen) på B-celler och framkallar B-cellsproliferation. Mutation i detta protein ger up phov till X-bundet hyper-IgM-syndrom (hypergammaglobulinemi).
A membrane glycoprotein and differentiation antigen expressed on the surface of T-cells that binds to CD40 ANTIGENS on B-LYMPHOCYTES and induces their proliferation. Mutation of the gene for CD40 ligand is a cause of HYPER-IGM IMMUNODEFICIENCY SYNDROME, TYPE 1.
