Target Background

Costimulates T-cell proliferation. May regulate myeloid cell activity in a variety of tissues.
Gene References into Functions
  1. overexpression of human CD200 in donor pigs could constitute a promising strategy for overcoming xenograft rejection. PMID: 28968355
  2. Our results support the fact that CD200 can be added to routine Chronic lymphoproliferative disorders panel as it is useful in subcategorizing them. However, inclusion of CD20 ABC to routine panel does not seem plausible but may be done for difficult diagnostic cases or where anti-CD20 therapy is planned. PMID: 29567884
  3. A diligent morphological examination to look for the presence of hairy cells along with flow cytometric immunophenotyping showing consistent bright expression of CD200, in addition to well-described characteristic immunophenotype, helps in correctly diagnosing the case. This can be further confirmed by the consistent presence of V600E point mutation in BRAF gene. PMID: 30197362
  4. CD200(+) and/or CD56(+) positive expression in B-ALL patients at diagnosis is a poor prognostic biomarker. PMID: 29161980
  5. CD200 was expressed in 97.3% of atypical chronic lymphocytic leukemia cases, whereas it was dimly expressed in only 6.1% of mantle cell lymphoma cases. PMID: 28713070
  6. CD200 and/or CD56 positive expression in B-ALL at diagnosis suggest a poor prognosis and may be associated with biological aggressiveness. PMID: 29144828
  7. downregulation of CD200 expression resulted in an imbalance of increased Th1 cytokine and decreased Th2 cytokine production in placental trophoblasts in preeclampsia PMID: 28940677
  8. This is the first report of CD200 mRNA and protein expression in patients with transitional cell carcinoma of the human bladder. TCC tissues showed significantly higher CD200 expression than normal bladder tissues. CD200 signals were also higher in metastasized compared to localized TCC. The data provide a strong indication for a putative role of CD200 in the immune-evasion of bladder cancer. PMID: 29715095
  9. Our data confirm a negative impact of ABCG2 and CD200 overexpression also in AML patients considered at favorable risk according to ELN cytogenetic/molecular classification. PMID: 28618016
  10. Residual CD200 activity may prevent completion of abortions via induction of Treg cells. In chronic histiocytic intervillositis, infiltrating maternal effector T cells may block Treg induction. An autocrine role for CD200-CD200R interaction versus inhibition of soluble CD200 by soluble CD200R is discussed. PMID: 28326648

  17. Our data suggest a negative impact of CD200 expression in cytogenetically-normal acute myeloid leukemia PMID: 28407515
  18. CD200 was expressed in 87% of the neuroendocrine neoplasms studied. CD200 is a relatively sensitive marker of neuroendocrine neoplasms and represents a potential therapeutic target in these difficult-to-treat malignancies. PMID: 28821198
  19. Up-regulation of CD200 in MDS predicts poor prognosis. PMID: 28152413
  20. this study shows that that CD200 suppresses the immune system's response to vaccines, and that blocking CD200 could improve the efficacy of cancer immunotherapy PMID: 27485078
  21. These results suggest that CD200S activates TAMs to become DC-like antigen presenting cells, leading to the activation of CD8(+) cytotoxic T lymphocytes, which induce apoptotic elimination of tumor cells. PMID: 27108386
  22. increased expression of CD200, expansion of suppressive Treg cells and elevation of cytokines might have a role in multiple myeloma progression PMID: 26033514

  24. data confirms that a functionally active CD200 extracellular moiety can be cleaved from the surface of CD200 expressing cells following ectodomain shedding PMID: 27111430
  25. CD200 is a poor prognostic factor for overall survival in multiple myeloma (MM) patients. Bone marrow CD3 lymphocytes from MM patients express CD200 protein in higher proportion than healthy donors. PMID: 26177431
  26. CD200 expression by cultured cultured bone marrow mesenchymal stem cells can be induced by both osteogenic and pro-inflammatory cytokines through the sole NF-kappaB pathway. PMID: 26773707
  27. suggest that microglial activation may be partially caused by CD47/signal regulatory protein-alpha- and CD200/CD200R-mediated reductions in the immune inhibitory pathways PMID: 27095555
  28. CD200 is up-regulated and may be a novel biomarker for the prognosis in cutaneous squamous cell carcinoma. PMID: 27035797
  29. CD200 expression is a useful marker for evaluation of the severity of PCM and that lack of CD200 expression may improve the sensitivity of PCM to therapy with new drugs. PMID: 26763359
  30. the combination of CD200 and CD148 may have a potential differential diagnostic value in leukemic B-CLPDs, especially between CLL and MCL. PMID: 25791119
  31. CD200-CD200R1 signaling may be required for human pregnancy success. PMID: 26123445
  32. CD200 signaling may play a key role in regulating macrophage polarization toward anti-inflammatory phenotypes PMID: 26670206
