From: Differential expression of P2X7 receptor and IL-1β in nociceptive and neuropathic pain
Exemplary illustration of P2X7 receptor expression. For quantitative analysis of the proportion of CD4+ cells (a) and P2X7R protein expression (b), cells were stained with PerCP-labeled antihuman CD4 antibody and FITC-labeled antihuman P2X7R antibody. We separately analyzed each subgroup by the mean fluorescence intensity (MFI) of P2X7R expression. Overlay histograms of representative results of P2X7R expression of one patient/healthy volunteer are displayed in histograms
