Abstract:
The cholinergic network affects various cellular functions including neurotransmission, and immune reactions. In Myasthenia Gravis (MG), diagnosis and symptomatic therapy are based on cholinergic modulation by acetylcholinesterase inhibitors (AChEI). In Alzheimer's disease (AD) a neurodegenerative disorder associated with inflammatory pathology, cholinergic systems cell loss occurs early. Treatments with special AChEI enhance cholinergic transmission and may act as anti-inflammatory agent via immunocompetent cells expressing alpha-7 acetylcholine receptor (AChR). In Multiple Sclerosis (MS) an inflammatory T-cell-mediated disease, demyelination and neurodegeneration follow neuroinflammation. MS treatment includes anti-inflammatory and immunomodulatory drugs. AChEI can induce cholinergic up-regulation with subsequent effect on neuroinflammation via alpha-7-AChR expressing cells. These effects are additional to the cognitive benefit induced by AChEI.

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
