When Viruses Talk through Extracellular Vesicles: a New Perspective on Sars‐Cov‐2‐Induced Neurodegeneration

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT SARS‐CoV‐2 infection is linked to persistent neurological symptoms Post‐Acute Sequelae SARS‐CoV‐2 (neuro‐PASC) and elevated risk of neurodegenerative disease, but molecular events connecting acute viral injury to long‐term CNS dysfunction remain unclear.

Introduction of ORF3a-Q57H SARS-CoV-2 Variant Causing Fourth Epidemic Wave of COVID-19, Hong Kong, China [PDF]

, 2021
We describe an introduction of clade GH severe acute respiratory syndrome coronavirus 2 causing a fourth wave of coronavirus disease in Hong Kong. The virus has an ORF3a-Q57H mutation, causing truncation of ORF3b. This virus evades induction of cytokine,

The Open Reading Frame 7b of the SARS‐CoV‐2 Disperse Trans‐Golgi and Activate the NLRP3 Inflammasome

Journal of Medical Virology, Volume 98, Issue 4, April 2026.
ABSTRACT Inflammasomes orchestrate the inflammatory response against bacterial and viral infections, thereby initiating the synthesis of pro‐inflammatory cytokines, mainly IL‐1β and IL‐18. SARS‐CoV‐2 infection induces an inflammatory response mediated by the activation of NLRP1 and NLRP3 inflammasomes.

Liquid–Liquid Phase Separation in Viral Infection and Immunology

MedComm, Volume 7, Issue 4, April 2026.
LLPS organizes viral replication and antiviral immunity. Viruses hijack LLPS to form replication factories and evade immune sensors, while hosts assemble LLPS‐driven signaling hubs (e.g., MAVS, RIG‐I, and SGs) to amplify interferon responses. Targeting these condensate interfaces offers novel therapeutic strategies against infectious diseases ...

SARS Accessory Proteins ORF3a and 9b and Their Functional Analysis

, 2009
The SARS coronavirus (CoV) positive-stranded RNA viral genome encodes 14 open reading frames (ORFs), eight of which encode proteins termed as “accessory proteins.” These proteins help the virus infect the host and promote virulence. In this chapter we describe some of our latest investigations into the structure and function of two such accessory ...

Extracellular Vesicle‐Delivered tRF‐His‐GTG‐1 Reprograms Neutrophil Lipophagy and Triggers Inflammation in COVID‐19

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study identifies platelet‐derived extracellular vesicles as key immunometabolic regulators in COVID‐19. The delivery of tRF‐His‐GTG‐1 to neutrophils activates TLR8mTOR signaling, disrupts lipophagy, and amplifies NET‐mediated inflammation. Importantly, targeting this axis restores neutrophil homeostasis, offering a potential therapeutic strategy ...

Unraveling Lysosomal Exocytosis: From Molecular Mechanisms to Physiological Functions

Traffic, Volume 27, Issue 1, March 2026.
Lysosomal exocytosis is propelled by specific molecular mechanisms that direct its microtubule‐dependent transport and subsequent fusion with the plasma membrane. This process fulfills essential physiological functions such as plasma membrane repair, maintenance of cellular homeostasis, and participation in signal transduction.

Immunization with Recombinant Accessory Protein-Deficient SARS-CoV-2 Protects against Lethal Challenge and Viral Transmission

Microbiology Spectrum, 2023
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to a worldwide coronavirus disease 2019 (COVID-19) pandemic. Despite the high efficacy of the authorized vaccines, there may be uncertain and unknown side effects or disadvantages ...

Analysis of 3.5 Million SARS-CoV-2 Sequences Reveals Unique Mutational Trends with Consistent Nucleotide and Codon Frequencies [PDF]

, 2023
Background: Since the onset of the SARS-CoV-2 pandemic, bioinformatic analyses have been performed to understand the nucleotide and synonymous codon usage features and mutational patterns of the virus. However, comparatively few have attempted to perform
