WebInterneurons are integral parts of enteric secretomotor pathways. Several types of myenteric neurons send axons to the submucosal plexus, including ISNs. In guinea-pig ileum, three readily defined classes of myenteric interneurons supply the submucosa, two contain ChAT, while the other contains VIP and neuronal nitric oxide synthase (nNOS). WebLowering mutant huntingtin selectively in striatal cholinergic interneurons with a virally-delivered zinc finger repressor protein normalized striatal acetylcholine release and intratelencephalic functional connectivity, revealing a node in the network underlying corticostriatal pathophysiology in a HD mouse model. WebHere, we show that acetylcholine release from cholinergic septohippocampal projections causes a long-lasting GABAergic inhibition of hippocampal dentate granule cells in vivo and in vitro. This inhibition is caused by cholinergic activation of hilar astrocytes, which provide glutamatergic excitation of hilar inhibitory interneurons. cox green uniform shop

WebThe cholinergic interneurons provide an ongoing acetylcholine (ACh) signal by firing action potentials tonically at about 5 Hz. A high concentration of acetylcholinesterase in the striatum rapidly terminates the ACh signal, and thereby minimizes desensitization of nicotinic acetylcholine receptors.
