WebAcetylcholine (ACh) is a small molecule neurotransmitter best known for its role at the neuromuscular junction , the synapse between a motor neuron and a muscle fiber. In the presynaptic terminal, acetylcholine is synthesized from acetyl coenzyme A (acetyl CoA) and choline via the enzyme choline acetyltransferase (ChAT). WebChronic intermittent hypoxia (CIH), the main pathophysiological characteristics of OSA, is closely related to cognitive dysfunction and may be mediated by alpha-7 nicotinic acetylcholine receptors (α 7nAChR). This study investigated the effects and clarified the mechanisms of α 7nAChR on the cognitive function of mice with CIH.
WebAcetylcholine (ACh) The cholinergic system, which is found in both neuronal and non-neuronal cells, forms a network that performs various complex functions in the body. The ChAT enzyme synthesizes ACh from the precursor molecules, choline ( 8 ).
