| I. Background | |
| CD40, a TNF receptor superfamily member, was initially identified on B lymphocytes. However, antigen presenting cells (APCs) such as monocytes, basophils, dendritic cells and non-immune cells like endothelial cells and epithelial cells have been found to express CD40. A wide variety of carcinoma cells also over-express CD40. Interaction with CD40 ligand (CD40L, CD154) on CD4+ T helper lymphocytes triggers the expression of intercellular adhesion molecule (ICAM) and other pro-inflammatory cytokines. CD40:CD40L signaling simultaneously increases activation of antigen-specific T cells. CD40 also activates NF-κB-dependent signaling in response to lipopolysaccharide (LPS) found on Gram negative bacterial pathogens. Furthermore, agonistic CD40 monoclonal antibodies have been shown to activate antigen presenting cells (APC) and promote anti-tumor T-cell responses in addition to fostering cytotoxic myeloid cells with the potential to control cancer in the absence of T-cell immunity. | |
