Abstract

Cholinergic neurons from the septum area, the vertical limb of the diagonal band of Broca, and the nucleus basalis of Meynert of postnatal 13-day-old rats were cultured with or without nerve growth factor (NGF) conditions. Total choline acetyltransferase (ChAT) activities, acetylcholine (ACh) contents, and survival numbers of cholinergic neurons in culture from each of three distinct regions were increased by NGF treatment, but little difference was found in cellular ChAT activities and ACh contents obtained in cultures with or without NGF. The result shows that NGF promotes the survival of cholinergic neurons from 13-day-old rats. Furthermore, the release of ACh from cultured neurons was investigated. The cells cultured with NGF showed a larger increase of the high K+-evoked ACh release than those cultured without NGF. However, NGF had no effect on spontaneous release. This suggests that NGF could regenerate and sustain the stimulation-evoked release mechanisms of ACh in cultured cholinergic neurons from postnatal rats.
