Data Examples
Detection of CD40/TNFRSF5 in Human Blood Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were stained with Mouse Anti-Human CD40/TNFRSF5 PE‑conjugated Monoclonal Antibody (Catalog # FAB6321P) and Mouse Anti-Human CD19 Fluorescein‑conjugated Monoclonal Antibody (Catalog # FAB4867F). Quadrant markers were set based on control antibody staining (Catalog # IC0041F). View our protocol for Staining Membrane-associated Proteins.

Background: CD40/TNFRSF5
CD40, also known as TNFRSF5, is a 45-50 kD type I transmembrane glycoprotein that belongs to the TNF receptor superfamily. Mature human CD40 is 257 amino acids (aa) in length, and consists of a 173 aa extracellular domain (ECD), a 22 aa transmembrane segment and a 62 aa cytoplasmic region. The ECD contains four cysteine-rich repeats, the second of which is considered crucial to ligand binding. Over aa 21-193, human CD40 shares 58% aa sequence identity with mouse CD40. Although not ubiquitously expressed, cells known to constitutively or inducibly express CD40 are large in number and include basal layer keratinocytes, adipocytes, CD8+ T cells, fibrocytes (circulating stem cells), monocytes, eosinophils, dendritic cells, pancreatic duct epithelium, astrocytes, smooth muscle cells, fibroblasts, vascular endothelial cells and B cells. There is at least one alternative splice form that shows a 38 aa substitution for aa 166-277, generating a soluble molecule. There are two "ligands" for CD40, the first being CD154/CD40L, and the second Borrelia, a spirochete that causes Lyme disease. CD40 ligation by CD154 has many outcomes, some of which are cell-specific. Ligation of CD40 on B cells (with IL-4) induces IgE production, while bone marrow stromal cell activation via CD40 promotes OPG secretion with concomitant bone formation. In addition, stimulation of CD40 on keratinocytes results in IL-8 and RANTES expression with subsequent leukocyte infiltration, while adipocyte activation via CD40 promotes local M1 polarization.
