Tlx3 controls cholinergic transmitter and Peptide phenotypes in a subset of prenatal sympathetic neurons.
The embryonic sympathetic nervous system consists of predominantly noradrenergic neurons and a very small population of cholinergic neurons. Postnatal development further allows target-dependent switch of a subset of noradrenergic neurons into cholinergic phenotype. How embryonic cholinergic neurons are specified at the prenatal stages remains largely unknown. In this study, we found that the e...
متن کاملCholine and cholinergic neurons.
Mammalian neurons can synthesize choline by methylating phosphatidylethanolamine and hydrolyzing the resulting phosphatidylcholine. This process is stimulated by catecholamines. The phosphatidylethanolamine is synthesized in part from phosphatidylserine; hence the amino acids methionine (acting after conversion to S-adenosylmethionine) and serine can be the ultimate precursors of choline. Brain...
متن کاملCharacterization of tissue-derived macromolecules affecting transmitter synthesis in rat spinal cord neurons.
Rat spinal cord cells maintained in neuron-rich cultures were exposed to extracts of skeletal muscle or to medium conditioned by non-neuronal cells. The conditioned media enhanced neuronal acetylcholine (ACh) synthesis, choline acetyltransferase activity, and protein synthesis, and decreased gamma-aminobutyric acid (GABA) synthesis. Muscle extract prepared from newborn rats produced similar enh...

متن کاملRegulation of cholinergic phenotype in developing neurons.
Specification of neurotransmitter phenotype is critical for neural circuit development and is influenced by intrinsic and extrinsic factors. Recent findings in rat hypothalamus in vitro suggest the role of neurotransmitter glutamate in the regulation of cholinergic phenotype. Here we extended our previous studies on the mechanisms of glutamate-dependent regulation of cholinergic phenotypic prop...
