In intact islets interstitial GABA activates GABA(A) receptors that generate tonic currents in α-cells. [PDF]

PLoS ONE, 2013
In the rat islets γ-aminobutyric acid (GABA) is produced by the β-cells and, at least, the α-cells express the GABA(A) receptors (GABA(A) channels). In this study, we examined in intact islets if the interstitial GABA activated the GABA(A) receptors.

Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

Advanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

Exosome‐mediated gut–brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives—A narrative review

Animal Models and Experimental Medicine, EarlyView.
The gut–brain axis is a bidirectional communication network between the intestines and brain, mediated by gut microbiota and exosomes, that regulates neuroinflammation, protein aggregation, and neuronal health processes central to neurodegenerative diseases.

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

Animal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Gut–Brain Axis Modulation by Short‐Chain Fatty Acids Exerts Disease‐Modifying Effects in a Murine Model of Drug‐Resistant Epilepsy

Annals of Neurology, EarlyView.
Objective Drug‐resistant epilepsy (DRE) remains a clinical challenge, as therapies modifying disease trajectory are lacking. Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short‐chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti‐inflammatory properties.

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Membranes and Synaptosomes Used to Investigate Synaptic GABAergic Currents in Epileptic Patients

Membranes
Among the most prevalent neurological disorders, epilepsy affects about 1% of the population worldwide. We previously found, using human epileptic tissues, that GABAergic neurotransmission impairment is a key mechanism that drives the pathological ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Task‐Related Aperiodic EEG (1/f) Activity in Autism

Autism Research, EarlyView.
ABSTRACT Autism has been hypothesized to involve atypicalities in the balance between neural excitation and inhibition (E/I). Aperiodic EEG activity, characterized by the 1/f exponent of the power spectrum, provides a proxy of cortical E/I dynamics. However, prior studies in autism report mixed findings regarding the slope of aperiodic activity.

Interaction of the Gut Microbiota and the Enteric Nervous System: Implications in Gastrointestinal Disorders Associated With Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social interaction, restricted interests, and repetitive behaviors. In addition to these core behavioral symptoms, gastrointestinal (GI) disorders are frequently reported, ranging from severe constipation to diarrhea.
