Postganglionic sympathetic neurons express endothelin.
Endothelin (ET) is a peptide originally identified as an endothelial-derived vasoconstrictor. It is now recognized that ET is produced by and acts on many other tissues including the brain and spinal cord, where it is believed to modulate neurotransmission. The present studies demonstrate that ET is synthesized by and secreted from postganglionic sympathetic neurons. With the use of Northern an...
متن کاملKv1.3 channels in postganglionic sympathetic neurons: expression, function, and modulation.
Kv1.3 channels are known to modulate many aspects of neuronal function. We tested the hypothesis that Kv1.3 modulates the function of postganglionic sympathetic neurons. RT-PCR, immunoblot, and immunohistochemical analyses indicated that Kv1.3 channels were expressed in these neurons. Immunohistochemical analyses indicated that Kv1.3 protein was localized to neuronal cell bodies, processes, and...
متن کاملInterleukin-17A increases neurite outgrowth from adult postganglionic sympathetic neurons.
Inflammation can profoundly alter the structure and function of the nervous system. Interleukin (IL)-17 has been implicated in the pathogenesis of several inflammatory diseases associated with nervous system plasticity. However, the effects of IL-17 on the nervous system remain unexplored. Cell and explant culture techniques, immunohistochemistry, electrophysiology, and Ca2+ imaging were used t...
متن کاملVascular-dependent effects of elevated glucose on postganglionic sympathetic neurons.
Perivascular sympathetic nerves are important determinants of vascular function that are likely to contribute to vascular complications associated with hyperglycemia and diabetes. The present study tested the hypothesis that glucose modulates perivascular sympathetic nerves by studying the effects of 7 days of hyperglycemia on norepinephrine (NE) synthesis [tyrosine hydroxylase (TH)], release, ...
متن کاملSympathetic postganglionic cholinergic fibres.
When the postganglionic fibres to the nictitating membrane are stimulated in a cat treated with reserpine, the membrane contracts. The contraction is increased after the injection of eserine and is abolished with atropine. Thus the fibres stimulated appear to be cholinergic. When the splenic nerve is stimulated in a cat treated with reserpine there is similar evidence of the presence of choline...
