Figure 10From: On the possible role of ERK, p38 and CaMKII in the regulation of CGRP expression in morphine-tolerant rats Immunohistochemical staining and distribution of nNOS-ir cells in the spinal cord dorsal horn (Aa). Double immunofluorescence staining revealed that nNOS is mostly enriched in NeuN-ir (arrows, Ad-f,) but not in GFAP- (green, Ab) or OX-42-ir (green, Ac) cells. B) nNOS-expressing cells also express CaMKII (arrows, Ba-c). Scale bars, 25 μm (Aa); 20 μm (Ab-f, Ba-c).Back to article page
