Fig. 7From: Preemptive intrathecal administration of endomorphins relieves inflammatory pain in male mice via inhibition of p38 MAPK signaling and regulation of inflammatory cytokinesRepresentative immunofluorescence staining revealed co-expression patterns of P-p38 MAPK with MOR. Double immunostaining of P-p38 MAPK (red) and MOR (green) was investigated in L4 DRG neurons of the control group, saline-treated CFA group, and endomorphins-treated CFA group. Arrows indicate co-expression. n = 4–6 animals/group, > 500 neurons per animal were assessed. Scale bar = 50 μmBack to article page
