Background Information
CD40 is a member of the tumor necrosis factor receptor superfamily. It is expressed in various immune cells, including B cells, macrophages, and dendritic cells. CD40 functions as a co-stimulatory receptor that interacts with its ligand, CD40L (CD154), primarily expressed on activated CD4+ T cells. This interaction is essential for T-cell activation, immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 signaling is mediated by recruitment of TRAFs (TNF receptor-associated factors) and NF-κB activation, supplemented by pathways such as PI3K/AKT, MAPKs, and JAK3/STATs. Additionally, circulating soluble CD40 levels are elevated in patients with chronic renal failure, chronic liver diseases, Alzheimer's disease, systemic sclerosis, and hematological malignancies.
