Con A and IL-2 stimulated mouse splenocytes (day 3) were stained with CD3ε APC and purified CD279 (clone 29F.1A12, left) or rat IgG2a, κ isotype control (right) followed by FITC anti-rat IgG. -
Fresh, frozen mouse spleen was stained with purified CD279 clone 29F.1A12 conjugated and detected with a Cy5 CODEX™ oligonucleotide duplex (red). Samples were counterstained with TCR FITC (green). Data generated at Akoya Biosciences, Inc. using the CODEX™ technology.

CD279, also known as programmed death-1 (PD-1), is a 50-55 kD glycoprotein belonging to the CD28 family of the Ig superfamily. PD-1 is expressed on activated splenic T and B cells and thymocytes. It is induced on activated myeloid cells as well. PD-1 is involved in lymphocyte clonal selection and peripheral tolerance through binding its ligands, B7-H1 (PD-L1) and B7-DC (PD-L2). It has been reported that PD-1 and PD-L1 interactions are critical to positive selection and play a role in shaping the T cell repertoire. PD-L1 negative costimulation is essential for prolonged survival of intratesticular islet allografts.
