Brain-derived neurotrophic factor (BDNF) was found to promote the survival of E17 rat embryo septal cholinergic neurons in culture, as assessed by a histochemical stain for acetylcholinesterase (AChE). A 2.4-fold increase in neuronal survival was achieved with 10 ng/ml BDNF. After initial deprivation of growth factor for 7 days, BDNF failed to bring about this increase, strongly suggesting that BDNF promotes cell survival and not just induction of AChE. BDNF was also found to increase the levels of cholinergic enzymes; choline acetyltransferase (ChAT) and AChE activities were increased by approximately 2-fold in the presence of 50 ng/ml BDNF. BDNF produced a 3-fold increase in the number of cells bearing the NGF receptor, as detected by the monoclonal antibody IgG-192. Although NGF had no additive effect with BDNF in terms of neuronal survival, suggesting that both act on a similar neuronal population, the combination of both produced an additive response, approximately a 6-fold increase, in ChAT activity.
