Previous … WebThe UC10-4B9 antibody can enhance T cell co-stimulation by blocking CTLA-4 interactions with the B7 co-receptors, favoring CD28 interactions. Additional reported applications … how to open int fileWebCTLA-4 is also known to bind to B7 ligands (CD80, CD86) and send inhibitory signaling to APCs by counteracting signaling generated by CD28. Thus, CTLA-4 binding to CD80 or CD86 (B7 molecules) inhibits T-cell activation and proliferation. This strategy can be used to target CD28 for designing immunosuppressive drugs. how to open install directory

"Web5 nov. 1993 · The B7-1 protein is a costimulator molecule that regulates interleukin-2 (IL-2) secretion by signaling through the pathway that uses CD28 and CTLA-4 (hereafter referred to as the CD28 pathway).
