Central non-opioid physiological and pathophysiological effects of dynorphin A and related peptides

V K Shukla et al. J Psychiatry Neurosci. 1992 Sep.

Abstract

Dynorphin A (Dyn A) and related opioid peptides derived from prodynorphin possess a high affinity for kappa opioid receptors, but they also bind to other opioid receptors (mu and delta) as well as to some non-opioid receptor sites. Although the physiological role of these peptides is not well established, recent experimental data pinpoint their particular involvement in physiological and pathophysiological conditions that relate to algesia, spinal cord injury and epilepsy. In this paper, we review data which support the concept that the non-opioid behavioral effects of Dyn A and related endogenous peptides which are observed under these conditions are physiologically and pathophysiologically relevant.
