Background
CD40,
also known as TNFRSF5, is a type I transmembrane glycoprotein member of the TNF receptor superfamily (1). Mature Cynomolgus Monkey CD40 consists of an extracellular
domain, a transmembrane domain, and a cytoplasmic domain (2). The extracellular domain (21-193 aa) of Cynomolgus
Monkey CD40 shares 96%, 58% and 56% amino acid (aa) sequence identity with human, mouse and
rat CD40, respectively. CD40 is expressed on the surface of B cells, dendritic
cells, macrophages, monocytes and platelets, as well as endothelial and
epithelial cells (4, 5). The
extracellular domain has the cysteine-rich repeat regions, which are
characteristic for many of the receptors of the TNF superfamily. Interaction
of CD40 with its ligand, CD40L, leads to the aggregation of CD40 molecules
resulting in the initiation of bidirectional intracellular signaling in both
CD40 and CD40L expressing cells (6). CD40
ligation by CD40L promotes B cell activation and T cell‑dependent humoral
responses (7, 8). CD40 serves multiple functions in both hematopoietic
and epithelial cancers and is a target for tumor immunotherapy (9, 10). Dysregulation of CD40/CD40L expression and
interactions contributes to the immune deficiency associated with HIV infection
and AIDS (11, 12). It is also implicated in the pathology of
multiple cardiovascular diseases including atherosclerosis, atherothrombosis,
and restenosis (13, 14).
