Intra-amygdala infusion of zeta inhibitory peptide attenuates neuropathic pain but not inflammatory pain in adult rats.
Abstract
Protein kinase Mζ (PKMζ), a typical brain-specific PKC isoform, has been shown to be critical in the maintenance of long-term potentiation and memory storage. Zeta inhibitory peptide (ZIP), a peptide with selective inhibition of PKMζ, has been used in relieving experimental neuropathic pain and disrupting memory. The aim of this study was to investigate the effects of intra-amygdalar infusion of ZIP on neuropathic pain induced by chronic constriction injury (CCI), and inflammatory pain induced by complete Freund's adjuvant (CFA) in adult rats.
