Kolin’in Merkezi ve Periferik Kolinerjik Nöronlarda ve Kolinerjik İletimdeki İşlevi

Kolin bir kuaterner amin olup, nörotrasmitter asetilkolinin ve membranın temel yapılarından fosfotidilkolin’in öncül maddesidir. Kolin ayrıca vücutta, metionin ve s-adenosilmetionin rejenerasyonu için gerekli metil guruplarının vericisi olan, betaine de metabolize olur. Bu derlemede esas olarak kolin’in cholinergic noronal görevlerindeki rolü üzerinde durulacaktır. Kolinerjik nöronların asetilkolin sentezi için kulandıkları kolin esas olarak kaynağı dolaşımdır. Dolaşımdaki kolin’in düzeyi 6-8 saatlik açlık sonrası 10 μM kadardır. Bu düzey yemek sonrası, gıdalardaki kolin‘in miktarına göre, 20-60 μM kadar yükselebilir. Farmakolojik dozlarda tedavi ile de kan kolin düzeyi 200-300 μM kadar yükselebilir. Kolin’i asetilkoline dönüştüren enzim kolinasetiltrasferaz enzimi substratı kolini zayıf bir şekilde doyurulmuş olduğundan plazmada kolin düzeyinin yükselmesi asetilkolin sentezini arttırır. Kolin, yeterince yüksek düzeylerinde 0,5-100 mM gibi , muskarinik ve nikotinik asetikolin reseptörleri ile agonist olarak da etkileşir. Kolin tedavisi nörotrasmitter asetilkolin’in sentez ve salıverilmesinde hızlanma ve merkezi ve periferik muskarinik ve nikotinik kolinerjik iletide yükselme ile sonuçlanır. Kolin, burada tartışılacak olan, kolinerjik nitelikte birçok fizyolojik, farmakolojik ve nörokimyasal etkiler oluşturur

Roles of Choline On Central and Peripheral Cholinergic Neurons and Cholinergic Neurotransmission

Choline, a quaternary amine, is an essential precursor for the neurotransmitter acetylcholine ACh and the major membrane constituent phosphatidylcholine PC . Choline is also metabolized to betaine, which provides a source of methyl groups for the regeneration of methionine and S-adenosylmethionine. The present review will mainly focus on the roles of choline on cholinergic neuronal functions. The main source of free choline for cholinergic neurons to synthesize acetylcholine is blood circulation. Plasma choline concentrations can vary over a six-fold range 10- 60 μM depending on the choline contents of the foods ingested. Choline concentrations in the circulation can increase up to 200-500 μM following treatment with pharmacological doses of choline. Since choline acetyltransferase [ChAT] , the enzyme that converts choline to ACh, is poorly saturated with its choline substrate, increases in plasma choline can enhance the formation and the release of ACh. Choline, at sufficiently high concentrations i.e., at 0,5-100 mM , aslo interacts with muscarinic and nicotinic acetylcholine receptors as an agonist. Choline treatments result with increases in neurotransmitter acetylcholine synthesis and release, and enhancements in central and peripheral muscarinic and nicotinic cholinergic neurotransmission. Choline produces several physiological, pharmacological and neurochemical effects in cholinergic nature which will be discussed here
