CD40


Also found in: Acronyms.

CD40

a type I transmembrane protein present on mature B cells, monocytes, dendritic cells, and epithelial cells involved in signal transduction leading to cell activation, proliferation, adhesion, and/or differentiation; expressed in B-cell chronic lymphocytic leukemias, lymphomas, and some carcinomas.

Its activation of CD40, a receptor in the dendritic cells of the immune system, enables those cells to stimulate certain weapons belonging to the immune system -- in this case, T cells -- allowing the immune system to selectively attack the cancer.
"It is the combination of the location of CD40, which seems to be a real sweet spot of activity, along with the ability to cluster the immune cell's receptors that gives such a potent response, one that we hope will be translated into the clinic to benefit patients," he added.

The thermal profile for amplification of CD40 C/T-1 was: 10 minutes initial denaturation at 95AdegC followed by 35 cycles including denaturation at 95AdegC for 45 seconds, annealing at 56AdegC for 1 minute, extension for 1 minute at 72AdegC and ultimate extension was carried out at 72AdegC for 7 minutes.
The phenotype analysis of Immature BMDC revealed that GM-[CSF.sup.lo] DC derived from culture as well as kit method expressed intermediate level of MHCII, decreased expression of CD86, and very low levels of CD40 (Figures 3 and 4).
Furthermore, the inflammatory cytokines TNF-[alpha], IL-1[beta], and TGF-[beta], as well as CD40, IL17a, IL-21, and CCL19, were closely related to the canonical and noncanonical NF-[kappa]B pathway.
Similar to MSCs, iPSC-MSC EVs did not significantly affect CD11c expression in SMGs but significantly decreased the expression of CD21 and CD40 and increased the IL10 expression (Figure 4(g)).

Protein concentrations of IL-1[beta], TNF-[alpha], PAI1, and CD40 were measured with standard ELISA kits (R&D Systems Europe, UK), according to the manufacturer's protocols.
CD154 and CD40 are other potent activators of T cells; monoclonal antibodies against either of these surface proteins have potential for application in transplant immunosuppression.
The university's Dr Nik Georgopoulos is developing a new form of treatment based on the protein molecule named CD40 (Cluster of Differentiation 40), which destroys cancerous tumours without harming healthy cell tissue.
Many signalings were coupled to CD40; for example, P38 MAPK/TNF[alpha] and PI3K/Akt /NF-kappab have been shown to enlarge systemic inflammation and promote differentiation of Th1 and Th17 (20).
