Torque Teno Virus Levels During Viral Respiratory Infections: The Interplay With Immune Dysregulation and Coagulopathy Biomarkers

Journal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Torque teno virus (TTV) is a ubiquitous, nonenveloped DNA virus of the Anelloviridae family and a proposed surrogate marker of immune competence. Although nonpathogenic, its replication reflects host immune status and is associated with immune dysregulation during respiratory viral infections (RVIs).

Increased Arrhythmia Risk in Long COVID: A Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
This meta‐analysis included 14 studies. Long COVID was associated with a higher risk of atrial fibrillation, sinus tachycardia, sinus bradycardia, and ventricular arrhythmias. Patients with more severe COVID‐19 infection were at a higher risk of developing arrhythmias in the long term.

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Associations of Fitness, Fatness Indices and Fit–Fat Index Variants With Cardiovascular and All‐Cause Mortality in Men

Obesity Science &Practice, Volume 12, Issue 1, February 2026.
ABSTRACT Background Fit–Fat Index (FFI), defined as the ratio of cardiorespiratory fitness (CRF) to waist‐to‐height ratio (WHtR), combines measures of fitness and fatness, and may offer a more accurate assessment of cardiometabolic risk than either component alone.

Stabilization versus flexibility: Detergent‐dependent trade‐offs in neurotensin receptor 1 GPCR ensembles

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Detergents provide essential membrane‐mimetic environments for studying G protein‐coupled receptors (GPCRs), but their molecular impact on receptor energetics remains incompletely understood. We combined ligand binding, thermostability measurements, and atomistic molecular dynamics to dissect detergent‐ versus ligand‐driven stabilization in a ...

Efficient and rapid isolation of native AMPA receptor complexes for cryo‐EM

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Isolating native ion channels for structural characterization is routinely achieved by extraction from membrane fractions of tissue with prolonged mild detergent treatment. AMPA receptors (AMPARs), glutamatergic receptors that mediate fast excitatory transmission and synaptic plasticity, are coassembled with diverse auxiliary subunits and ...
