Cancer cells often overexpress PD-L1 or PD-L2, allowing them to suppress T cell activation, evade the host immune response, and proliferate. Thus, disrupting the PD-1 co-inhibitory pathways may be an effective approach to developing anti-cancer therapies, as well as other immune diseases like multiple sclerosis, arthritis, lupus, and type I diabetes. The overexpression of PD-1 in this cell line allows for the study of PD-1 antibodies and other novel therapeutics.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eCell Signaling\u003c\/span\u003e\n\u003cp\u003eThe PD-1 CHO cell line is a recombinant clonal stable CHO-K1 cell line constitutively expressing human PD-1 receptor (accession number: NM_005018).
