Minocycline prevents the development of neuropathic pain, but not acute pain: possible anti-inflammatory and antioxidant mechanisms

SSV Padi, SK Kulkarni - European journal of pharmacology, 2008 - Elsevier
Glia, particularly astrocytes and microglia, are known to play an important role in central
sensitization and are strongly implicated in the exaggerated pain states. In the present study …

Activated microglia contribute to the maintenance of chronic pain after spinal cord injury

BC Hains, SG Waxman - Journal of Neuroscience, 2006 - Soc Neuroscience
Traumatic spinal cord injury (SCI) results not only in motor impairment but also in chronic
