Figure 3

Morphine induces phenotype shifts of local macrophages. The infiltration of F4/80+iNOS+ M1 macrophages (A) and F4/80+CD206+ M2 macrophages (B) was evaluated on PODs 2 and 7. (C) The numbers of total F4/80, F4/80+iNOS+, and F4/80+CD206+ macrophages were counted. Scale bar, 25 μm. *P < 0.05 (two-way ANOVA followed by Bonferroni post-hoc testing). Each column represents mean ± SEM (n = 6 for each group). Veh; vehicle (PBS), Mor; morphine 10 μg, Nal; naloxone 5 μg.
