WebSelective blockade of CD28 is a promising therapy to inhibit pathogenic alloimmunity. However, evaluation of this approach in transplantation has been very limited. Using a novel nonactivating single-chain Fv-based reagent (α28scFv), we have investigated the role of CD28 and cytotoxic T lymphocyte antigen 4 (CTLA-4) in a murine cardiac transplant … WebALLISON CLT 3461/TEREX; ALLISON 4000 OFF-HIGHWAY; ALLISON 5000/6000; ALLISON 8000/9000; ALLISON TX-100/ MILITARY; ALLISON TORQUE CONVERTER; …

WebJim Allison, Ph.D., discovered the first known immune checkpoint, CTLA-4, in 1995. By blocking CTLA-4 in the laboratory, Allison learned that T cells could be set free to attack … WebCTLA-4 is a second receptor for B7 family members, that shares 30% homology with CD28, but that binds both B7-1 and B7-2 with higher affinity. A third ligand for CTLA-4 and presumably CD28 has been implicated recently in mouse, the binding of which also promotes costimulation of T lymphocytes. bithalter holzheft
