Dose‐Dependent Autophagic Dysfunction and CCR5‐Mediated Neuroinflammation Drive Arsenic Trioxide‐Induced Cortical Neurodegeneration in Mice

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
Exposure to arsenic trioxide (As2O3) in humans is associated with dose‐dependent cortical neurodegeneration with convergent pathological mechanisms. Low and medium dose exposure induces adaptive autophagy via PI3K/AKT/mTOR suppression and high dose exposure leads to mTOR hyperactivation, autophagic failure, microglial neuroinflammation and excitotoxic ...

Multi‐Omics Insights Into Circulating T‐Cell Metabolic Reprogramming and Treg Dysfunction in Moyamoya Disease

MedComm, Volume 7, Issue 11, November 2026.
The comprehensive study design is illustrated. A multi‐omics approach was used to characterize T‐cell metabolic alterations in MMD. By integrating mass cytometry (CyTOF), single‐cell RNA sequencing (scRNA‐seq), bulk RNA‐seq, metabolomics, and flow cytometry, we aimed to elucidate metabolic reprogramming in circulating T cells and Treg dysfunction in ...

Opioid Modulation of Major Neurotransmitter Systems: Acute, Chronic, and Withdrawal Effects

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Opioids are widely used but also frequently misused drugs that affect multiple neurotransmitter systems, including dopaminergic, glutamatergic, GABAergic, serotonergic, and cholinergic pathways. Opioid‐induced neuroadaptations depend on the duration of drug exposure, with distinct changes also emerging following drug discontinuation.

The Pros & Cons of Measuring Plasma Ammonia in the Management of Patients With Cirrhosis: An ISHEN Debate

Liver International, Volume 46, Issue 11, November 2026.
ABSTRACT Ammonia is a nitrogenous molecule which is primarily generated in the gastrointestinal tract. The neurotoxicity of ammonia plays a critical role in the liver's regulation of circulating ammonia levels. In liver disease, an increase in blood ammonia has been long implicated in the pathogenesis of hepatic encephalopathy (HE), a neurological ...
