Figure 7From: On the possible role of ERK, p38 and CaMKII in the regulation of CGRP expression in morphine-tolerant rats Double immunofluorescence staining shows that phosphorylated CaMKII (p-CaMKII, green) is expressed in CGRP-expressing (red) DRG neurons. Arrows show their co-localization (yellow; asterisk). Scale bar, 20 μm.Back to article page
