Cell-mediated immune responses are initiated by T lymphocytes that are themselves stimulated by cognate peptides bound to MHC molecules on antigen-presenting cells (APC).
T-cell activation is generally self-limited as activated T cells express receptors such as PDCD-1 that mediate inhibitory signals from the APC.
PDCD-1 can bind two different but related ligands, PDL-1 and PDL-2.
PDL-1 is a B7-related protein that inhibits cell-mediated immune responses by reducing the secretion of IL-2 and IL-10 from memory T cells.
This suggests that PDL-1 may be useful in reducing allogenic CD4+ memory T-cell responses to endothelial cells, thereby reducing the likelihood of host immune responses to allografts.
At least two isoforms of PDL-1 are known to exist; this antibody is specific to the larger isoform.
PDL-1 antibody has no cross-reactivity to PDL-2.
