CD40
CD40 (TNFRSF5) is a co-stimulatory receptor of the TNF receptor superfamily and the central orchestrator of humoral and cellular immunity. CD40 is a 45-50 kDa type I transmembrane protein with four extracellular cysteine-rich domains, expressed on B cells, dendritic cells, macrophages, monocytes, epithelial and endothelial cells, fibroblasts and various carcinomas. Its ligand CD40L (CD154), transiently expressed on activated CD4+ T cells and platelets, triggers receptor trimerization and recruitment of TRAF2/3/5/6, activating canonical and non-canonical NF-κB, MAPK, JAK3-STAT3 and PI3K pathways. In B cells, CD40 signaling drives germinal center formation, immunoglobulin class switching, somatic hypermutation, memory B-cell and plasma-cell differentiation; in dendritic cells, it licenses antigen presentation and interleukin-12 production. CD40-CD40L defects cause X-linked hyper-IgM immunodeficiency, whereas sustained CD40 signaling contributes to atherosclerosis, autoimmune inflammation and B-cell lymphomas; agonistic CD40 antibodies and CD40L blockers are both therapeutic development tracks in cancer and autoimmunity.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
