The cholinergic differentiation factor ciliary neurotrophic factor (CNTF) suppresses noradrenergic properties while inducing cholinergic and peptidergic properties in sympathetic neurons. In the rat, this includes suppression of the noradrenergic enzymes tyrosine hydroxylase and dopamine beta-hydroxylase. Lower enzyme levels result in part from suppression of gene transcription, but the mechanisms are unknown. We found that ciliary neurotrophic factor decreased the transcriptional activator Phox2a in neuroblastoma cells and cultured sympathetic neurons, suggesting that the loss of Phox2a is part of the mechanism by which CNTF suppresses tyrosine hydroxylase and dopamine beta-hydroxylase. Consistent with this model, Phox2a is suppressed in rat cholinergic sympathetic neurons where noradrenergic enzymes decrease, but is not altered in mouse cholinergic neurons where these enzymes remain high.
