Figure 2From: CD200 in CNS tumor-induced immunosuppression: the role for CD200 pathway blockade in targeted immunotherapy CD200R antagonist blocks MDSC expansion and tumor suppressive effects. A. Murine glioma GL261 was incubated with naïve splenocytes in a trans-well plate +/- CD200R antagonist and analyzed for MDSC expansion and cytokine production. B. Naïve splenocytes were pulsed with purified CD200 +/- CD200R antagonist and analyzed for MDSC expansion and arginase-I production. Error bars are ± SEM, statistical significance was determined using an unpaired T-test, *p < 0.05, **p < 0.001.Back to article page
