Young Human Cholinergic Neurons Respond to Physiological Regulators and Improve Cognitive Symptoms in an Animal Model of Alzheimer’s Disease

Frontiers in Cellular Neuroscience, 2017
The degeneration of cholinergic neurons of the nucleus basalis of Meynert (NBM) in the basal forebrain (BF) is associated to the cognitive decline of Alzheimer’s disease (AD) patients. To date no resolutive therapies exist. Cell-based replacement therapy

Cholinergic receptor labelling specific irreversible binding of bromoacetylcholine to cholinergic receptors at neuromuscular junctions

European Journal of Pharmacology, 1974
This study shows that (a) the slopes of dose-response curves of bromoacetylcholine (BrACh) and acetylcoline (ACh) were the same; (b) the dose-response curves of BrACh to contract superfused chick biventer cervicis and frog rectus abdominis muscles were shifted to the right by d-tubocurarine in a parallel fashio; and (c) the responses of BrACh were not ...

Involvement of Nitric Oxide in Depolarization-Induced Suppression of Inhibition in Hippocampal Pyramidal Cells during Activation of Cholinergic Receptors

Journal of Neuroscience, 2007
Several types of neurons are able to regulate their synaptic inputs via releasing retrograde signal molecules, such as endocannabinoids or nitric oxide (NO).

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Periodontitis presenting among betel quid users: A case series

Clinical Advances in Periodontics, EarlyView.
Abstract Background Betel leaf chewing habit has been studied extensively, as it has been an ancient practice in many Asian countries. Although betel leaf has been reported to have potential beneficial properties, it has also been shown to have a strong association with oral diseases, including periodontitis. This case series addresses the presentation

Hippocampus and Entorhinal Cortex Recruit Cholinergic and NMDA Receptors Separately to Generate Hippocampal Theta Oscillations

Cell Reports, 2017
Summary: Although much progress has been made in understanding type II theta rhythm generation under urethane anesthesia, less is known about the mechanisms underlying type I theta generation during active exploration.

An in vivo biosensor for neurotransmitter release and in situ receptor activity. [PDF]

, 2010
Tools from molecular biology, combined with in vivo optical imaging techniques, provide new mechanisms for noninvasively observing brain processes. Current approaches primarily probe cell-based variables, such as cytosolic calcium or membrane potential ...

Promising Prodiginins Biological Activities

Chemistry &Biodiversity, EarlyView.
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

Undifferentiated and differentiated PC12 cells protected by huprines against injury induced by hydrogen peroxide. [PDF]

PLoS ONE, 2013
Oxidative stress is implicated in the pathogenesis of neurodegenerative disorders and hydrogen peroxide (H2O2) plays a central role in the stress. Huprines, a group of potent acetylcholinesterase inhibitors (AChEIs), have shown a broad cholinergic ...
