16. The mechanism underlying ESA might be associated with enhanced expression of CD200 and CD200R in the trophoblast, leading to an upregulation of the immune response during the first trimester of pregnancy.

17. The expression of CD200R as well as B7-H4 co-stimulatory molecules on CD14(+) cells were significantly higher in cord blood when compared with peripheral blood.

18. Measurement of sCD200 and/or sCD200R1 may prove a useful and rapid means of monitoring subjects at risk of bone loss.

19. [review] CD200R1 is comparable to other pathogen-targeted inhibitory receptors; its signaling pathway is utilized by a diverse number of pathogens and represents a novel targeting strategy for infectiouis diseases.

20. Mesenchymal stem cells, through the expression of CD200, play a major role in the regulation of bone resorption and bone physiology and the CD200-CD200R couple could be a new target to control bone diseases.

Mouse (Murine) CD200 Receptor 1 (CD200R1) Interaktionspartner

1. blockade of the endogenous ligand CD200 prevented the tumorigenic effect of CD200R-expressing myeloid cells in the tumor microenvironment, whereas agonistic anti-CD200R has no effect on tumor development

2. Study in CD200R-/- mice revealed that CD200R deficiency leads to enhanced bacterial burden in neutrophils. CD200R-deficient neutrophils display significantly reduced reactive oxygen species production (ROS), suggesting that CD200R-mediated ROS production in neutrophils is necessary for limiting F.tularensis colonization and proliferation. Overall, data show that CD200R promotes the antimicrobial properties of neutrophils.

3. This study demonstrated that loss of CD200R1 led to high mortality, increased rates of post-stroke infection, and enhanced entry of peripheral leukocytes into the brain after ischemia, with no increase in infarct size.

4. Foxp3 is essential for beneficial outcome of the microglial response and depends upon signalling by the immunoglobulin CD200 through its receptor (CD200R)

5. In adoptive therapy of disseminated leukemia, CD200R-CD28-transduced leukemia-specific CD8 T cells eradicated otherwise lethal disease more efficiently than wild-type cells and bypassed the requirement for interleukin-2 administration to sustain in vivo activity.

6. we revealed a critical role for CD200R signaling in limiting the growth and metastasis of CD200(+) tumors.

7. CD200R signaling inhibits pro-angiogenic gene expression by macrophages and suppresses choroidal neovascularization.

8. Data show that neutrophil infiltration of tissues was markedly decreased in CD200 antigen (tg) transgenic animals and increased in CD200 receptor 1 CD200R1(-/-) knockout mice.
