B cell surface antigen CD40

The CD40 gene encodes a TNF receptor located on B lymphocytes. Coupling of CD40 and the appropriate ligand CD40LG on T lymphocytes is essential to the maturation of B lymphocytes to produce a proper immune response. Mutations cause autosomal recessive hyper-IgM syndrome 3.
