CD40 / TNFRSF5抗体背景综述
Human tumor necrosis factor receptor superfamily member 5, also known as CD40 and TNFRSF5, is a member of the TNF receptor superfamily which are single transmembrane-spanning glycoproteins, and plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 contains 4 cysteine-rich repeats in the extracellular domain, and is expressed in B cells, dendritic cells, macrophages, endothelial cells, and several tumor cell lines. The cognate interaction between CD40 and CD40 ligand (CD154) on T cells activates NF-kappa B, Jun N-terminal kinase, and Janus kinase signal transducers and activators of transcription pathways. Several different TRAF proteins (Adaptor proteins) have been identified to serves as mediators of the signal transduction. In addition, CD40 / CD40L interaction is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. Defects in CD40 result in hyper-IgM immunodeficiency type 3 (HIGM3), an autosomal recessive disorder characterized by an inability of B cells to undergo isotype switching, as well as an inability to mount an antibody-specific immune response, and a lack of germinal center formation.
