Muscarinic Receptors and Their Antagonists in COPD: Anti-Inflammatory and Antiremodeling Effects
Muscarinic receptors are expressed by most cell types and mediate cellular signaling of their natural ligand acetylcholine. Thereby, they control numerous central and peripheral physiological organ responses to neuronal activity.

Protein connectivity in chemotaxis receptor complexes [PDF]
The chemotaxis sensory system allows bacteria such as Escherichia coli to swim towards nutrients and away from repellents. The underlying pathway is remarkably sensitive in detecting chemical gradients over a wide range of ambient concentrations. Interactions among receptors, which are predominantly clustered at the cell poles, are crucial to this ...

Light‐Activated Pharmacological Tools for Exploring the Cholinergic System
ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to

Amyloidosis in central and enteric nervous system contribute to congenic impairment and gastrointestinal dysmotility in Alzheimer's Disease (AD). 5xFAD mice, a transgenic mouse model of AD, mimic the amyloidosis in central nervous system but lacking amyloidosis in enteric nervous system. Abstract Background Alterations in gastrointestinal (GI) function

The present study was undertaken to clarify how spinal muscarinic receptors are involved in the antinociceptive effects in thermal stimulation. Intrathecal (i.t.) injection of the muscarinic agonist McN-A-343 inhibited the tail-flick response to noxious ...

Effect of Neuromodulation of Short-Term Plasticity on Information Processing in Hippocampal Interneuron Synapses [PDF]
Neurons in a micro-circuit connected by chemical synapses can have their connectivity affected by the prior activity of the cells. The number of synapses available for releasing neurotransmitter can be decreased by repetitive activation through depletion of readily releasable neurotransmitter (NT), or increased through facilitation, where the ...

Molecular Tools to Study and Control Dopaminergic Neurotransmission With Light
ABSTRACT Dopaminergic neurotransmission is involved in several important brain functions, such as motor control, learning, reward‐motivated behavior, and emotions. Dysfunctions of dopaminergic system may lead to the development of various neurological and psychiatric disorders, like Parkinson's disease, schizophrenia, depression, and addictions ...

KV7 Channels Regulate Firing during Synaptic Integration in GABAergic Striatal Neurons
Striatal projection neurons (SPNs) process motor and cognitive information. Their activity is affected by Parkinson’s disease, in which dopamine concentration is decreased and acetylcholine concentration is increased.

Muscarinic receptor signaling in the pathophysiology of asthma and COPD
Anticholinergics are widely used for the treatment of COPD, and to a lesser extent for asthma. Primarily used as bronchodilators, they reverse the action of vagally derived acetylcholine on airway smooth muscle contraction.
