Intraspinal transplantation of GABAergic neural progenitors attenuates neuropathic pain in rats: A pharmacologic and neurophysiological evaluation

► Dysfunctional GABA signaling may contribute to neuropathic pain. ► Transplantation of GABAergic neuronal progenitors improved pain-related behavior. ► Grafted GABAergic cells reduced hyperexcitability of dorsal horn neurons. ► Antinociceptive effect of grafts is mediated through activation of GABA receptors.
