Disease

[TNR5_HUMAN] Defects in CD40 are the cause of immunodeficiency with hyper-IgM type 3 (HIGM3) [MIM:606843]. A rare immunodeficiency syndrome characterized by normal or elevated serum IgM levels with absence of IgG, IgA, and IgE. It results in a profound susceptibility to bacterial infections.^[1]

Function

[TNR5_HUMAN] Receptor for TNFSF5/CD40LG.

Publication Abstract from PubMed

Current clinical anti-CD40 biologic agents include both antagonist molecules for the treatment of autoimmune diseases, and agonist molecules for immuno-oncology, yet the relationship between CD40 epitope and these opposing biological outcomes is not well defined. This report describes the identification of potent antagonist domain antibodies (dAbs) that bind to a novel human-CD40 specific epitope which is divergent in the CD40 of non-human primates. A similarly selected anti-cynomolgus-CD40 dAb recognizing the homologous epitope is also a potent antagonist. Mutagenesis, biochemical, and X-ray crystallography studies demonstrate that the epitope is distinct from that of CD40 agonists. Both the human-specific and cynomolgus-specific molecules remain pure antagonists even when formatted as bivalent Fc-fusion proteins, making this an attractive therapeutic format for targeting hCD40 in autoimmune indications.
