Cholinergic Inhibition of Neocortical Pyramidal Neurons [PDF]

The Journal of Neuroscience, 2005
Acetylcholine (ACh) is a central neurotransmitter critical for normal cognitive function. Here we show that transient muscarinic acetylcholine receptor activation directly inhibits neocortical layer 5 pyramidal neurons. Using whole-cell and cell-attached recordings from neurons in slices of rat somatosensory cortex, we demonstrate that transient ...

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

Advanced 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

Adenosine Inhibits the Excitatory Synaptic Inputs to Basal Forebrain Cholinergic, GABAergic and Parvalbumin Neurons in mice

Frontiers in Neurology, 2013
Coffee and tea contain the stimulants caffeine and theophylline. These compounds act as antagonists of adenosine receptors. Adenosine promotes sleep and its extracellular concentration rises in association with prolonged wakefulness, particularly in the ...

Spatial Transcriptomics Reveals a T Cell‐Mediated Microglial Activation Axis of Immune Checkpoint Inhibition‐Related Adverse Events in the Brain

Advanced Science, EarlyView.
Immune checkpoint inhibition (ICI) reshapes the hippocampal neuroimmune niche. Spatial transcriptomic profiling and human brain histological analyses identify neuroinflammation and altered neuronal and glial programs. Notably, T cell depletion prevents ICI‐driven microglial activation, establishing the T cell–microglia crosstalk axis as a driving ...

Co‐activation of Selective Nicotinic Acetylcholine Receptor Subtypes Is Required for Neuroprotection against Alzheimer's Disease

Advanced Science, EarlyView.
ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Sacral Neural Crest‐Derived Extracellular Vesicles Promote Pelvic Ganglion Repair Through Anti‐Pyroptotic Effects Involving ANXA1–FPR2 Signaling

Advanced Science, EarlyView.
Extracellular vesicles derived from human pluripotent stem cell‐derived sacral neural crest cells promote repair of injured major pelvic ganglia and improve colorectal function. These vesicles reduce oxidative stress and pyroptosis, with ANXA1–FPR2 signaling contributing to their protective effects, and show a favorable therapeutic profile compared ...

Astrocyte‐Associated ABCA1/APOE Responses Accompany Hippocampal Lipid Remodeling and Ectopic Neuronal Accumulation During Epileptogenesis

Advanced Science, EarlyView.
During kainic acid‐induced epileptogenesis, astrocyte‐associated ATP‐binding cassette transporter A1 (ABCA1) and apolipoprotein E (APOE) responses accompany ectopic neurons and exploratory lipid alterations. In separate cohorts, bexarotene pretreatment and treatment on days 14–21 are associated with fewer ectopic hilar neurons and lower chronic seizure
