Cholinergic neurons

The process of developmental cell specification underlying neuronal identity and function is an area of great current interest. There has been significant progress in identifying the cholinergic neurons origins, commonalities in molecular markers, cholinergic neurons, and physiological properties of the cholinergic neurons. Currently, we are aware of a number of key factors that promote cholinergic fate during development.

The enzyme choline acetyltransferase ChAT is responsible for synthesizing ACh from acetyl-CoA and choline in the cytoplasm and the vesicular acetylcholine transporter VAChT uptakes the neurotransmitter into synaptic vesicles. Following depolarization, ACh undergoes exocytosis reaching the synaptic cleft, where it can bind its receptors, including muscarinic and nicotinic receptors.

Acetylcholine, a neurotransmitter secreted by cholinergic neurons, is involved in signal transduction related to memory and learning ability. The pathogenesis of AD is complex and remains unclear, being affected by various factors. The cholinergic hypothesis is the earliest theory about the pathogenesis of AD. Cholinergic atrophy and cognitive decline are accelerated in age-related neurodegenerative diseases such as AD. In addition, abnormal central cholinergic changes can also induce abnormal phosphorylation of ttau protein, nerve cell inflammation, cell apoptosis, and other pathological phenomena, but the exact mechanism of action is still unclear. Due to the complex and unclear pathogenesis, effective methods to prevent and treat AD are unavailable, and research to explore novel therapeutic drugs is various and active in the world. This review summaries the role of cholinergic signaling and the correlation between the cholinergic signaling pathway with other risk factors in AD and provides the latest research about the efficient therapeutic drugs and treatment of AD. AD is a major cause of dementia which is a common disease among the elderly, starting with an irreversible decline in episodic memory and then a more general decline in overall cognitive ability [ 2 , 3 ].

Cholinergic modulation of brain activity is fundamental for awareness and conscious sensorimotor behaviours, but deciphering the timing and significance of acetylcholine actions for these behaviours is challenging. The widespread nature of cholinergic projections to the cortex means that new insights require access to specific neuronal populations, and on a time-scale that matches behaviourally relevant cholinergic actions. A consequence of this re-shaping was disrupted adaptation of the sensory-evoked responses, suggesting a critical role for acetylcholine during sensory discrimination behaviour. Sweyta Lohani, Andrew H. Moberly, … Jessica A. Acetylcholine ACh is a widespread neurotransmitter and neuromodulator long known to act throughout the central nervous system across a variety of circuitries and timescales 1 , 2 , 3 , 4 , 5 , 6 , 7.

The loss of BFCNs can lead to impaired cholinergic neurotransmission, abnormal synaptic function and changes in structural lipid metabolism [ 76 ]. In the central nervous system, ACh has a variety of effects as a neuromodulator for plasticity, arousal, and reward. Key Terms choline acetyltransferase : Abbreviated as ChAT, this is an enzyme that is synthesized within the body of a neuron. Neuroinflammation is important in the onset and progression of neurodegenerative diseases such as AD. This suggests that the induction of directed differentiation of pluripotent stem cells and the addition of BFCNs is a feasible research direction, providing a potential application prospect for the study of disease treatment.

However, degeneration of central cholinergic neurons may occur, given the anti-inflammatory and antioxidant effects of neuronal glial cholinergic signaling, leading to impaired learning, memory, sleep regulation and attention [ 29 ]. Hoch, R. Houser C. The role of choline acetyltransferase is to join Acetyl-CoA to choline, resulting in the formation of the neurotransmitter acetylcholine. ACh receptors are classified, according to agonist selectivity and pharmacology, as either muscarinic or nicotinic receptors.
