Retrograde Labeling of Different Distribution Features of DRG P2X2 and P2X3 Receptors in a Neuropathic Pain Rat Model

Figure 5

Expression and size distribution of P2X2-positive cells among total and FG-positive DRG neurons between the control and CCI groups. (a) P2X2-positive fluorescence images of total and FG-positive DRG between the control and CCI groups (200x, scale is 50 μm). (b) The percentages of the expression and size distribution of P2X2-positive cells to total and FG-positive DRG neurons between the control and CCI groups. There was an especially significant difference between the control and CCI groups for small cells. , compared with the control group, .
