Abstract
These studies have been undertaken to evaluate the role of the brain noradrenergic and dopaminergic pathways in the regulation of the secretion of thyrotropin-releasing hormone (TRH) in the central nervous system (CNS) and pancreas of the neonatal rat. When CNS stores of norepinephrine (NE) were selectively reduced by the subcutaneous administration of the dopamine-β-hydroxylase inhibitor FLA-63, TRH concentrations were significantly reduced throughout the brain. However, when CNS stores of both NE and dopamine (DA) were depleted by the subcutaneous administration of the tyrosine hydroxylase inhibitor α-methyl-ρ-tyrosine (α-MT), TRH concentrations in the brain were not significantly altered.
