Origin of acetylcholine antagonism in ELIC, a bacterial pentameric ligand-gated ion channel

Communications Biology, 2022
A structural and functional study of the prokaryotic ligand-gated ion channel, ELIC, provides insight into the origin of agonism and antagonism at nicotinic acetylcholine receptors.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Mechanisms of spinal glial activation in chemotherapy‐induced peripheral neuropathy: Focus on microglia and astrocytes

Ibrain, EarlyView.
Chemotherapy‐induced peripheral neuropathy (CIPN) remains a major clinical challenge, with central sensitization considered an important pathological mechanism in its occurrence and persistence. This review focuses on spinal astrocytes and microglia, systematically summarizing the pathological mechanisms of spinal glial cells involved in CIPN caused by

"Warming yang and invigorating qi" acupuncture alters acetylcholine receptor expression in the neuromuscular junction of rats with experimental autoimmune myasthenia gravis

Neural Regeneration Research, 2016
Myasthenia gravis is an autoimmune disorder in which antibodies have been shown to form against the nicotinic acetylcholine nicotinic postsynaptic receptors located at the neuromuscular junction.

Nicotinic acetylcholine receptors and cancer

Biomedical Reports, 2016
Nicotine, the primary addictive constituent of cigarettes, is believed to contribute to cancer promotion and progression through the activation of nicotinic acetylcholine receptors (nAChRs), which are membrane ligand-gated cation channels. nAChRs activation can be triggered by the neurotransmitter Ach, or certain other biological compounds, such as ...

Weizmannia coagulans XY2 Mitigates Copper Neurotoxicity via Gut–Brain Axis Modulation of Tryptophan Metabolism and Oxidative‐Inflammatory Crosstalk

iMetaOmics, EarlyView.
Copper interferes with tryptophan metabolism and 5‐HT levels by modulating intestinal flora. Intestinal barrier breakdown and inflammatory response trigger nerve damage under copper exposure. W. coagulans XY2 alleviates copper‐induced neurotoxicity by targeting a multi‐dimensional “tryptophan metabolism‐antioxidant defense‐gut‐brain axis” network.

The Role of Nicotinic Receptors on Ca²⁺ Signaling in Bovine Chromaffin Cells

Current Issues in Molecular Biology
Chromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Dendritic spine density of prefrontal layer 6 pyramidal neurons in relation to apical dendrite sculpting by nicotinic acetylcholine receptors

Frontiers in Cellular Neuroscience, 2015
Prefrontal layer 6 (L6) pyramidal neurons play an important role in the adult control of attention, facilitated by their strong activation by nicotinic acetylcholine receptors.

Placental‐Derived Connective Tissue Matrix Mediates Murine Recurrent Laryngeal Nerve Regeneration

The Laryngoscope, EarlyView.
Placentally derived connective tissue matrix (pd‐CTM) innately contains various neurotrophic, angiogenic, anti‐inflammatory, and tissue remodeling cytokines. In this mouse model of unilateral vocal fold paralysis, we investigate its effects on recurrent laryngeal nerve (RLN) regeneration and reinnervation of the right thyroarytenoid (TA) muscle after ...
