Figure 7From: Aberrant CD200/CD200R1 expression and function in systemic lupus erythematosus contributes to abnormal T-cell responsiveness and dendritic cell activity CD200 expression on early apoptotic cells was higher than on live cells. CD200 expression but not CD4 expression on early apoptotic cells was significantly higher than on live cells (annexin V-PI-) (n = 45) (median 14.5, interquartile range 8.5 to 28.7 vs. 6.30, 3.60 to 9.70; P < 0.001). PI, propidium iodide.Back to article page
