    basic FUNCTION
  • pleiotropic modulator of immune response including germinal center formation
  • Ig isotype switching and T cell activation in part by activation of NKFBs through binding to TRAF proteins and JAK3
  • suppressor of apoptosis throught NFKB dependent upregulation of BCL2 family members
  • CD40 signaling is critical for innate and adaptive immunity against pathogens
  • regulator of retinal inflammation and neurovascular degeneration
  • adipocyte CD40 may contribute to obesity-related inflammation and insulin resistance
  • delivers signals regulating diverse cellular responses, including proliferation, differentiation, growth suppression, and cell death
  • CD40 signaling is an active termination signal for germinal center reaction
  • required for T cell-dependent humoral immunity, but it can also contribute to the pathogenesis of autoimmunity and B cell malignancy
  • its activation can reverse immune suppression and drive antitumor T cell responses
  • role for the CD40 pathway in regulating the immune reaction and fibrosis associated with pancreatic ductal adenocarcinoma by reeducation of tumor-associated macrophage
  • sCD40LG/CD40 axis triggers NFKB1 activation in platelets
  • activation of CD40 on B cells, macrophages, and dendritic cells by its ligand CD40LG is essential for the development of humoral and cellular immune responses
  • CD40 self-assembly modulates signaling, possibly by maintaining the receptor in a quiescent state
  • CD40-mediated maintenance of immune homeostasis in the adipose tissue microenvironment
  • CD40-induced signalling through ligation with its natural ligand (CD40LG) is dependent on recruitment of TRAF molecules to the cytoplasmic domain of the receptor
  • has a pivotal role in B-cell-mediated immunity through various effector pathways including AKT1 kinase
  • CD4(+) T cells directly influence naive B cell development via CD40 signaling
  • CD40 expression on the surface of B lymphocytes is essential for their biological function and fate decision
  • co-stimulatory protein that is involved in T helper cell polarization and is found on the surface of antigen-presenting cells

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with TRAF2 and TRAF6 adaptor proteins that are positive regulators of CD40 signaling required to activate downstream kinase cascades and transcription factors
  • RIPK1 links the immunoregulatory CD40 receptor to apoptotic signaling in carcinomas
  • TRAF3 can serve as a negative regulator of CD40 signaling
  • CD40/CD40LG interaction induces SELE dependent adhesion of leukocytes to human endothelial cells and reduces endothelial cell migration by inhibiting the Akt/eNOS signaling pathway
  • in platelets, soluble CD40LG induces association of CD40 with its adaptor protein the TNFR associated factor 2 and triggers phosphorylation of CHUK
  • NFKB1 signaling pathway, which involves both NFKBIA and CHUK, plays an important role in platelet CD40 signaling, activation and aggregation in response to sCD40LG
  • novel role of a scaffolding protein SPAG9 in the regulation of surface CD40 expression and fine-tuning of dendritic cells function
  • TNFSF12 inhibits TRAF2-mediated CD40 signaling by destabilization of CD40 signaling complexes
  • CD40LG is released from T-cells by ADAM10 and ADAM17 upon CD40 ligation
  • FAF1 was able to interact with CD40, and CD40 ligation induced FAF1 expression in an NFKB1-dependent manner
  • NEDD4 constitutively interacts with CD40 and mediates K63-linked ubiquitination of TRAF3
  • ERK-1/2 inhibition or MAPK14 overexpression inhibited CD40-induced PTPN6 activation
  • novel role of SPAG9 scaffold protein in the bridging of CD40LG-triggered CD40 internalization and CD40-dependent signaling in splenic B lymphocytes
  • SQSTM1 is a critical regulator in CD40-mediated NFKB1 signaling via TRAF6
