WebCTLA-4 is homologous to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA-4 binds CD80 and CD86 with greater affinity and avidity than CD28 thus enabling it to outcompete CD28 for its ligands. WebThe CTLA-4 protein is primarily expressed on T cells, including CD8 + cytotoxic T cells, CD4 + helper T cells, and CD4 + /FoxP3 + regulatory T cells (1,2). CTLA-4 protein competes with CD28 for B7.1 (CD80) and …
