Figure 5. DRG CCR2-immunoreactivity. Presence of CCR2-immunoreactive DRG cells in wild-type (a) but not in CCR2 knockout (b) mice. CCR2-immunoreactivity (c; f; i) occurred largely in TRPV1-positive neurons (d, g, j) as illustrated by merged images from epifluorescence (e; h) or confocal microscopy (k). Scale bar indicates 100 mm for a and b. DRG: dorsal root ganglia
