WebThe response of peripheral T lymphocytes (T cell) is controlled by multiple checkpoints to avoid unwanted activation against self-tissues. Two opposing costimulatory receptors, CD28 and CTLA-4, on T cells bind to the same ligands (CD80 and CD86) on antigen-presenting cells (APCs), and provide positive and negative feedback for T-cell activation, respectively. WebThe B7:CD28/CTLA-4 Pathway. CD80 (B7-1) and CD86 (B7-2) are expressed as cell surface molecules by APCs and are responsible for delivering additional or second signals to T cells when they interact with their ligands CD28 and CD152 (CTLA-4). CD28 is expressed constitutively by T cells, while CD152 is only expressed later in the activation …

"WebThe ligands for CD28 are CD80 (B7/BB1 or B7-1) and CD86 (B7-2). In addition to binding to CD28, both CD80 and CD86 also bind to the inhibitory protein CTLA-4, which is a CD28 homolog expressed on activated T cells and, especially, regulatory T cells (Tregs) (Walker, 2013). CD28 is also known to bind to ICOS. " - Cd28 and cd80
