Detection of mineralocorticoid receptor (MR) with pain signaling molecules TRPV1, CGRP, Nav1.8, and trkA in dorsal root ganglia (DRG) of control rats. a–d Double immunofluorescence confocal microscopy of MR (red fluorescence) with TRPV1, CGRP, Nav1.8, and trkA (green fluorescence) in DRG sections (Bar = 40 μm). a–d The majority of MR-IR DRG sensory neuron express TRPV1, CGRP, Nav1.8, and trkA in control animals (Bar = 40 μm). Data are expressed as means ± SD; n = 7–12
