The role of nitric oxide in the dorsomedial periaqueductal gray (dmPAG) column in cardiovascular responses in urethane‐anesthetized male rats

open access: yesAnimal Models and Experimental Medicine, Volume 5, Issue 6, Page 557-564, December 2022., 2022
In the current study, after anesthetized rat with urethan the femoral artery was cannulated, then its head was mounted on a stereotaxic instrument and drugs (saline‐NAME, L‐Arg, and L_Arg+ L‐NAME) microinjected into the dmPAG and cardiovascular responses that recorded by a Power lab were evaluated.

Is There a Canonical Cortical Circuit for the Cholinergic System? Anatomical Differences Across Common Model Systems

open access: yesFrontiers in Neural Circuits, 2018
Acetylcholine (ACh) is believed to act as a neuromodulator in cortical circuits that support cognition, specifically in processes including learning, memory consolidation, vigilance, arousal and attention. The cholinergic modulation of cortical processes

T-cell derived acetylcholine aids host defenses during enteric bacterial infection with Citrobacter rodentium. [PDF]

open access: yes, 2019
The regulation of mucosal immune function is critical to host protection from enteric pathogens but is incompletely understood. The nervous system and the neurotransmitter acetylcholine play an integral part in host defense against enteric bacterial ...

Inhibition of nicotinic acetylcholine receptors, a novel facet in the pleiotropic activities of snake venom phospholipases A2.

open access: yesPLoS ONE, 2014
Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis

Sex‐Specific Genetic Variants are Associated With Coronary Endothelial Dysfunction

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundEndothelial dysfunction is an early stage of atherosclerosis. Single‐nucleotide polymorphisms (SNPs) have been associated with vascular dysfunction, cardiac events, and coronary artery remodeling.

α3β4∗ Nicotinic Acetylcholine Receptors Strongly Modulate the Excitability of VIP Neurons in the Mouse Inferior Colliculus

open access: yesFrontiers in Neural Circuits, 2021
The inferior colliculus (IC), the midbrain hub of the central auditory system, receives extensive cholinergic input from the pontomesencephalic tegmentum.

Resolution of complex fluorescence spectra of lipids and nicotinic acetylcholine receptor by multivariate analysis reveals protein-mediated effects on the receptor's immediate lipid microenvironment [PDF]

open access: yesPMC Biophysics 2008, 1:6, 2009
Analysis of fluorescent spectra from complex biological systems containing various fluorescent probes with overlapping emission bands is a challenging task. Valuable information can be extracted from the full spectra, however, by using multivariate analysis (MA) of measurements at different wavelengths.

Spontaneous Lipid Binding to the Nicotinic Acetylcholine Receptor in a Native Membrane [PDF]

open access: yes, 2021
The nicotinic acetylcholine receptor (nAChR) and other pentameric ligand-gated ion channels (pLGICs) are native to neuronal membranes with an unusual lipid composition. While it is well-established that these receptors can be significantly modulated by lipids, the underlying mechanisms have been primarily studied in model membranes with only a few ...

Transient receptor potential canonical type 3 channels control the vascular contractility of mouse mesenteric arteries [PDF]

open access: yes, 2014
Transient receptor potential canonical type 3 (TRPC3) channels are non-selective cation channels and regulate intracellular Ca2+ concentration. We examined the role of TRPC3 channels in agonist-, membrane depolarization (high K+)-, and mechanical ...

Transcutaneous Vagus Nerve Stimulation Regulates the Cholinergic Anti-inflammatory Pathway to Counteract 1, 2-Dimethylhydrazine Induced Colon Carcinogenesis in Albino wistar Rats

open access: yesFrontiers in Pharmacology, 2019
The present work was undertaken to study the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on 1, 2-dimethyhydrazine (DMH) induced colon cancer and role of the cholinergic anti-inflammatory pathways (CAP) in the same.
