Intrinsic pH chemosensitivity of acutely dissociated medullary serotonergic and retrotrapezoid neurones

The Journal of Physiology, EarlyView.
Abstract figure legend Central respiratory chemoreceptors (CRCs) are critical for maintaining normal systemic levels of pH and PCO2. A CRC must respond to pH via intrinsic mechanisms. Here we quantified intrinsic chemosensitivity of medullary 5‐HT neurones and retrotrapezoid nucleus (RTN) neurones using acute dissociation.

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

The Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

DNA methylation potential: dietary intake and blood concentrations of one-carbon metabolites and cofactors in rural African women. [PDF]

, 2013
BACKGROUND: Animal models show that periconceptional supplementation with folic acid, vitamin B-12, choline, and betaine can induce differences in offspring phenotype mediated by epigenetic changes in DNA. In humans, altered DNA methylation patterns have

Harnessing Natural Killer Cells: From Neuroimmunology to Novel Therapies for Central Nervous System Diseases

MedComm, Volume 7, Issue 10, October 2026.
This review delineates the multifaceted roles of natural killer (NK) cells in the central nervous system, spanning direct cytolysis, immunoregulation, and crosstalk with the brain microenvironment. We evaluate the translational potential and challenges of NK cell immunotherapies for a spectrum of neurological conditions.

Maternal nutritional status, C1 metabolism and offspring DNA methylation: a review of current evidence in human subjects. [PDF]

, 2011
: Evidence is growing for the long-term effects of environmental factors during early-life on later disease susceptibility. It is believed that epigenetic mechanisms (changes in gene function not mediated by DNA sequence alteration), particularly DNA ...

Muscarinic agonists for schizophrenia: Bridging preclinical evidence and clinical enthusiasm

British Journal of Pharmacology, Volume 183, Issue 19, Page 5701-5731, October 2026.
Abstract Antipsychotic drugs targeting dopamine receptors have been used to treat schizophrenia for decades, primarily alleviating positive symptoms such as hallucinations and delusions. However, they provide limited benefit for cognitive and negative symptoms—major contributors to poor outcomes—and are frequently associated with significant side ...

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation

Advanced Science, Volume 13, Issue 50, 7 September 2026.
A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Maternal‐Fetal Administration of Risdiplam Partially Rescues the SMNΔ7 Mouse Model of Spinal Muscular Atrophy

Annals of Neurology, Volume 100, Issue 3, Page 584-599, September 2026.
Objective Spinal muscular atrophy (SMA) is caused by deletions or mutations in the survival motor neuron 1 (SMN1) gene and subsequent reduction in the expression of survival motor neuron (SMN) protein. The disease is characterized by degeneration of α motor neurons and subsequent muscle atrophy.

Development of Cholinergic Traits in the Quail Ciliary Ganglion: Expression of Choline Acetyltransferase-like Immunoreactivity

, 1990
The avian ciliary ganglion is a parasympathetic ganglion derived from the neurol crest whose neurons provide cholinergic innervation to the eye. Here, we describe the time course of appearance and the morphology of cholinergic cells in the ciliary ...
