Spinal protein kinase M ζ underlies the maintenance mechanism of persistent nociceptive sensitization.

Sensitization of the pain pathway is believed to promote clinical pain disorders. We hypothesized that the persistence of a sensitized state in the spinal dorsal horn might depend on the activity of protein kinase M ζ (PKMζ), an essential mechanism of late long-term potentiation (LTP). To test this ... View More
