Associated Diseases (KEGG IDs)Systemic lupus erythematosus 2 (SLEB2) [MIM:605218]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. {ECO:0000269|PubMed:12402038}. Disease susceptibility is associated with variations affecting the gene represented in this entry.
General Description of PD1 .
PD1, or CD279/PDCD1 (programmed cell death-1 protein), is a type I transmembrane receptor expressed on activated T-cells, B-cells, and myeloid cells. Engagement of PD1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function. Anti-PDCD1 is a marker of angioimmunoblastic lymphoma.also pro¬duce responses in nonimmunogenic cancers such as non–small-cell lung and colon cancers, broadening their scope beyond classic immunogenic tumors like melanoma and renal cell cancer.

PD1 Information for Pathologists


Also known as CD279. Coinhibitory receptor of lymphocytes / other immune system cells. Controls lymphocyte activation by providing negative signals in conjunction with signals from lymphocyte antigen receptors (Future Oncol 2011;7:929). Expressed by germinal center associated helper T cells; inhibits T cell activity (Hum Pathol 2009;40:1715). Expressed by CD8+ T cells, associated with CD8 activation (AIDS Res Hum Retroviruses 2012;28:465).

Common Uses By Pathologists:

Differentiate primary cutaneous CD4 small / medium sized pleomorphic T cell lymphoma and cutaneous pseudo-T cell lymphomas (PD-1 positive) from other cutaneous T cell lymphomas (usually PD-1 negative, Am J Surg Pathol 2012;36:109). PD-1+ rosettes of T cells around neoplastic cells is relatively specific for nodular lymphocyte predominant Hodgkin lymphoma (Hum Pathol 2009;40:1715).
