Systemic minocycline differentially influences changes in spinal microglial markers following formalin-induced nociception.

In the present study, intraperitoneal administration of minocycline attenuated enhancing nociceptive behaviors in those rats receiving dual formalin injections (5% formalin followed at 7 days later by 1% formalin). The minocycline treatment did not prevent the increase in OX-42 and MHC class I labeling and morphological changes, but significantly attenuated… CONTINUE READING
