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

open access: yesPLoS 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 ...

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

open access: yesEuropean 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 ...

A Novel Sparse Cellular Labeling System with Tunable Gradients and Long‐Term Stability

open access: yesAdvanced Science, EarlyView.
The Tri‐M (Multi‐recombinase, Multi‐recognition site, and Multi‐nested) sparse cellular labeling system, built upon competitive recombination, integrates transgenic mice with viral injection to achieve tunable and long‐term stable sparse labeling of specific cell types with region selectivity, from sparse populations to individual cells, facilitating ...

The role of spinal adrenergic receptors on the antinociception of ginsenosides in a rat postoperative pain model [PDF]

open access: yesKorean Journal of Anesthesiology, 2013
BackgroundThe effect of spinal adrenergic and cholinergic receptors on the anti-nociceptive effect of intrathecal ginsenosides was determined in a rat postoperative pain model.MethodsCatheters were placed into the intrathecal space of male Sprague-Dawley

GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

Nrsn1–Smarcc1 Coupling Regulates Neural Stem Cell Differentiation and Chronic‐phase Recovery After Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
In the post‐stroke brain, Foxa2 induces the transcriptional upregulation of Nrsn1 in NSCs. Nrsn1 functionally couples with Smarcc1, modulating its nuclear availability and protein abundance, thereby influencing Smarcc1‐associated regulatory programs linked to neuronal lineage commitment. Through this coupling, Nrsn1 promotes the differentiation of NSCs

Cholinergic receptors in aging and Alzheimer's disease

open access: yesProgress in Neuro-Psychopharmacology and Biological Psychiatry, 1986
Although Alzheimer's disease (AD) is a disorder involving multiple neurotransmitter systems, the basal forebrain cholinergic system (Ch system) is severely and consistently affected in this condition. In both animals and man, the nature of age-associated alterations in the Ch system is unclear. In addition, available studies of cholinergic receptors in

Heterogenous Cholinergic Nicotinic Receptors in the CNS

open access: yes, 1988
Multiple nicotinic binding sites are found in mammalian brain. Several nicotinic agonists and antagonists have been used to characterize the nicotinic binding sites.

Autonomic Nerve Fiber Compositions of Zygomaticotemporal and Lacrimal Nerves: A Cadaveric Immunohistochemical Analysis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
Key Points Zygomaticotemporal (ZTN) and lacrimal nerves (LN) both carried sympathetics and parasympathetics ZTNs had more parasympathetics than LNs, but markers varied significantly within and between nerves LN parasympathetics to the lacrimal gland may mitigate dry eye after vidian ...

Prolonged cholinergic enrichment influences regional cortical activation in early Alzheimer's disease [PDF]

open access: yes, 2008
Neuroimaging studies of cholinesterase inhibitor (ChEI) treatment in Alzheimer's disease (AD) indicate that the short and long term actions of ChEIs are dissimilar. fMRI studies of the ChEI rivastigmine have focused on its short term action.
