Potential revival of cholinesterase inhibitors as drugs in veterinary medicine

open access: yesFrontiers in Veterinary Science, 2023
The cholinergic system is involved in the regulation of all organ systems and has acetylcholine (ACh) as almost its only neurotransmitter. Any substance is called cholinergic if it can alter the action of acetylcholine. Cholinesterases (ChEs) are enzymes

Alterations in the cholinergic system after frontal cortical infarction in rat brain: Pharmacological magnetic resonance imaging of muscarinic receptor responsiveness and stereological analysis of cholinergic forebrain neurons

open access: yesNeurobiology of Disease, 2011
Vascular cognitive impairment has been related to dysfunction of the central cholinergic system. Studies exploring the putative relationship between vascular cognitive impairment and cholinergic dysfunction have largely been aimed at symptomatic ...

Cholinergic cells in the nucleus basalis of mice express the N-methyl-D-aspartate-receptor subunit NR2C and its replacement by the NR2B subunit enhances frontal and amygdaloid acetylcholine levels [PDF]

open access: yes, 2006
It is known that glutamatergic and cholinergic systems interact functionally at the level of the cholinergic basal forebrain. The N-methyl-D-aspartate receptor (NMDA-R) is a multiprotein complex composed of NR1, NR2 and/or NR3 subunits.

Complete morphologies of basal forebrain cholinergic neurons in the mouse

open access: yeseLife, 2014
The basal forebrain cholinergic system modulates neuronal excitability and vascular tone throughout the cerebral cortex and hippocampus. This system is severely affected in Alzheimer's disease (AD), and drug treatment to enhance cholinergic signaling is ...

Immunohistochemical study of the brainstem cholinergic system in the alpaca (Lama pacos) and colocalization with CGRP

open access: yesEuropean Journal of Histochemistry, 2021
Several cholinergic regions have been detected in the brainstem of mammals. In general, these regions are constant among different species, and the nuclear complement is maintained in animals belonging to the same order.

Longitudinal Alzheimer’s Degeneration Reflects the Spatial Topography of Cholinergic Basal Forebrain Projections

open access: yesCell Reports, 2018
Summary: The cholinergic neurons of the basal forebrain (BF) provide virtually all of the brain’s cortical and amygdalar cholinergic input. They are particularly vulnerable to neuropathology in early Alzheimer’s disease (AD) and may trigger the emergence

Changes in neuromuscular structure and functions of human colon during ageing are region-dependent [PDF]

open access: yes, 2018
Objective: To determine if human colonic neuromuscular functions decline with increasing age.Design: Looking for non-specific changes in neuromuscular function, a standard burst of electrical field stimulation (EFS) was used to evoke neuronally mediated (

Cooperative Glutamatergic and Cholinergic Mechanisms Generate Short-Term Modifications of Synaptic Effectiveness in Prepositus Hypoglossi Neurons [PDF]

open access: yes, 2005
To maintain horizontal eye position on a visual target after a saccade, extraocular motoneurons need a persistent (tonic) neural activity, called "eye-position signal," generated by prepositus hypoglossi (PH) neurons.
