Herpesvirus reactivation in COVID-19: clinical evidence, mechanistic insights, and research gaps

Frontiers in Immunology
Herpesviruses establish lifelong latency and can reactivate when antiviral immune surveillance is compromised. Since the onset of COVID-19 pandemic, reactivation of multiple human herpesviruses has increasingly been documented, particularly in patients ...

Waking Up the Sleepers: HIV Latency and Reactivation [PDF]

, 2008
In a patient infected with HIV-1, the presence of latently infected cells from which the virus can be reactivated and rekindle HIV infection in the patient necessitates lifelong administration of antiretroviral treatment.

A Molecularly Defined Midbrain Circuit Mechanism for Sound‐Driven Defensive Behavior and Anxiety

Advanced Science, EarlyView.
Schematic diagram showing the Cbln2+ ICx–dPAG circuit for sound‐driven defensive and anxiety‐like behaviors. ABSTRACT The innate defense behaviors in response to threatening sounds play a fundamental role in survival. However, the neural circuits that detect threat‐relevant auditory cues and transform them into defensive behaviors remain poorly defined.

Human cytomegalovirus-encoded G protein-coupled receptor (GPCR) UL78 regulates viral reactivation

Journal of Virology
Human cytomegalovirus (CMV) is a ubiquitous pathogen that establishes lifelong, latent infection in hematopoietic cells. Immune-competent individuals are usually asymptomatic for disease. However, immune dysregulation in latently infected individuals can

Latency, Integration, and Reactivation of Human Herpesvirus-6

Viruses, 2017
Human herpesvirus-6A (HHV-6A) and human herpesvirus-6B (HHV-6B) are two closely related viruses that infect T-cells. Both HHV-6A and HHV-6B possess telomere-like repeats at the terminal regions of their genomes that facilitate latency by integration into

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

Advanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

Advanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.

Circulating Exosomes Drive Persistent Neuronal Dysfunction in Post‐Herpetic Neuralgia Patients

Annals of Neurology, EarlyView.
Proposed model of exosome‐mediated neuronal dysfunction in post‐herpetic neuralgia (PHN). (1) Circulating, non‐pathogenic exosomes maintain homeostatic processes in healthy skin, where sensory nerve fibers innervate the epidermis and dermis. (2) During acute zoster, reactivating varicella zoster virus (VZV) travels down neurites to the skin causing ...

Epidemiological Survey and Genomic Insights Into Ostreid Herpesvirus 1 Transmission in the Blood Clam Anadara broughtonii in China (2019–2025)

Animal Research and One Health, EarlyView.
Seven‐year surveillance reveals a cold‐adapted OsHV‐1 lineage in blood clams, with disease onset at 13°C—3–5°C lower than in oysters—and identifies asymptomatic carriers and facility effluent as key transmission routes. ABSTRACT Ostreid herpesvirus 1 (OsHV‐1) poses a major threat to bivalve aquaculture, but its impact on blood clams (Anadara ...
