Acetylcholine receptors are not functionally independent

Biophysical Journal, 1986
Analysis of current recordings from acetylcholine-activated channels has largely rested so far on the hypothesis of independence, which states that the opening of one channel does not influence that of its neighbors. We have submitted this assumption to several tests, using as experimental material single channel currents from rat myotubes.

Tumor‐Associated Sympathetic Nerves Promote the Progression of Epstein‐Barr Virus‐Positive Diffuse Large B‐Cell Lymphoma

Advanced Science, EarlyView.
Sympathetic nerve innervation promotes the progression of Epstein‐Barr virus‐positive diffuse large B‐cell lymphoma (EBV+ DLBCL) via β2‐adrenergic receptors. The discovery of enhanced nerve infiltration and β2AR expression reveals a novel mechanism and highlights the sympathetic–β2AR axis as a promising target for therapeutic intervention in EBV+ DLBCL.

Rates and Equilibria for a Photoisomerizable Antagonist at the Acetylcholine Receptor of Electrophorus Electroplaques [PDF]

, 1985
Voltage-jump and light-flash experiments have been performed on isolated Electrophorus electroplaques exposed simultaneously to nicotinic agonists and to the photoisomerizable compound 2,2'-bis-[α-(trimethylammonium)methyl]-azobenzene (2BQ).

Nicotinic Acetylcholine Receptor Signaling in Tumor Growth and Metastasis

Journal of Oncology, 2011
Cigarette smoking is highly correlated with the onset of a variety of human cancers, and continued smoking is known to abrogate the beneficial effects of cancer therapy.

Scanning curves and kinetics of the acetylcholine / acetylcholine receptor hysteresis [PDF]

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988
The high affinity binding of the neurotransmitter acetylcholine (AcCh) to the nicotinic acetylcholine receptor (nAcChR) of the electric organ of Torpedo californica exhibits a pronounced hysteresis and scanning loops. Dialysis conditions lead to an equilibrium binding curve which is coincident with the upper hysteresis branch; K = 5 × 10−9M, 4° C; and ...

Hypoglycemia Induces Diabetic Macrovascular Endothelial Dysfunction via Endothelial Cell PANoptosis, Macrophage Polarization, and VSMC Fibrosis

Advanced Science, EarlyView.
This study investigates hypoglycemia‐induced diabetic macrovascular endothelial dysfunction. It reveals that hypoglycemia triggers ZBP1‐dependent PANoptosis of endothelial cells, proinflammatory polarization of macrophages, and fibrosis of vascular smooth muscle cells (VSMCs) in diabetic mice.

The miR-182-5p/FGF21/acetylcholine axis mediates the crosstalk between adipocytes and macrophages to promote beige fat thermogenesis

JCI Insight, 2021
A dynamically regulated microenvironment, which is mediated by crosstalk between adipocytes and neighboring cells, is critical for adipose tissue homeostasis and function.

Structure and function of an acetylcholine receptor

Biophysical Journal, 1982
Structural analysis of an acetylcholine receptor from Torpedo californica leads to a three-dimensional model in which a "monomeric" receptor is shown to contain subunits arranged around a central ionophoretic channel, which in turn traverses the entire 110 A length of the molecule.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

Advanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

Functional Characterization of a Novel Class of Morantel-Sensitive Acetylcholine Receptors in Nematodes. [PDF]

PLoS Pathogens, 2015
Acetylcholine receptors are pentameric ligand-gated channels involved in excitatory neuro-transmission in both vertebrates and invertebrates. In nematodes, they represent major targets for cholinergic agonist or antagonist anthelmintic drugs. Despite the
