Programmed cell death 1 (PD1) is a cell surface membrane protein of the immunoglobulin superfamily. It is expressed on the surface of activated T cells, B cells, macrophages, myeloid cells and a subset of thymocytes. PD1 functions as an inhibitory cell surface receptor which is involved in the regulation of T-cell function during immunity and tolerance. It is also a possible cell death inducer in association with other factors. Monoclonal antibodies targeting PD-1 that boost the immune system are being developed for the treatment of cancer.
