From: Morphine-induced changes in the function of microglia and macrophages after acute spinal cord injury
Quantification of microglia/macrophages expressing CD206 (M2 marker) and KOR. Morphine significantly increases the number of CD206+ microglia (A) and CD206+ macrophages (C) after 3 days of administration. Morphine administration also increases the number of CD206 + microglia and macrophages expressing KORs (B and D). Results shown as Mean ± S.E.M. *p < 0.05, n = 6
