Fusogenic structural changes in arenavirus glycoproteins are associated with viroporin activity

bioRxiv, 2023
Many enveloped viruses enter host cells by fusing with acidic endosomes. The fusion activity of multiple viral envelope glycoproteins does not generally affect viral membrane permeability.

Searching for Blockers of Dengue and West Nile Virus Viroporins

Viruses, 2022
Flavivirus infections, such as those caused by dengue and West Nile viruses, emerge as new challenges for the global healthcare sector. It has been found that these two viruses encode ion channels collectively termed viroporins. Therefore, drug molecules that block such ion-channel activity can serve as potential antiviral agents and may play a primary

The Significance of cGAS‐STING Signaling in Response to Oncogenic Viruses

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT The cyclic GMP‐AMP synthase (cGAS)‐stimulator of interferon genes (STING) signaling pathway, as a key DNA sensor, plays a significant role in the regulation of innate immune responses. This pathway can be activated by sensing abnormal DNA, and is of great significance for resisting the invasion of pathogenic microorganisms and maintaining ...

Design and Synthesis of Novel Imidazo[4,5‐c]pyridine Derivatives, Evaluation of Their Activity Against Hepatitis C Virus and In Silico Prediction of Their Binding Mode to NS4B Protein

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
A series of 18 novel imidazo[4,5‐c]pyridines was synthesized, and their anti‐HCV activity was evaluated. Compound 30b was identified as the most promising one, with EC50 = 6.61 µM. Molecular docking studies indicated the NS4B protein of the HCV as a potential target of these derivatives.

Oligomeric states of an Influenza-encoded PB1-F2 viroporin

bioRxiv, 2023
Influenza Viruses have always been a major health concern due to their highly contagious nature. The PB1-F2 viroporin encoded by the influenza A virus is known to be a pro-apoptotic protein involved in cell death induction of the host immune cells.

Regulation of the ER Stress Response by the Ion Channel Activity of the Infectious Bronchitis Coronavirus Envelope Protein Modulates Virion Release, Apoptosis, Viral Fitness, and Pathogenesis

Frontiers in Microbiology, 2020
Coronavirus (CoV) envelope (E) protein is a small structural protein critical for virion morphogenesis and release. The recently characterized E protein ion channel activity (EIC) has also been implicated in modulating viral pathogenesis.

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, Volume 13, Issue 42, 28 July 2026.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Stable expression of SARS-CoV-2 envelope viroporin promotes intracellular calcium depletion in human cells: relevance for endoplasmic reticulum stress, cell proliferation, pluripotency and lineage differentiation.

Cell Calcium
SARS-CoV-2 infection affects the respiratory system but also many tissues and organs that may be adversely compromised. Accordingly, recent evidence has assessed virus ability to infect different cell phenotypes, translate viral proteins and promote ...

SARS‐CoV‐2 and Cancer Biology: Exploring the Mechanistic Links

Cancer Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background Five years after the emergence of SARS‐CoV‐2 and the declaration of the COVID‐19 pandemic, the long‐term implications of COVID‐19 for cancer biology remain incompletely understood. Beyond the major disruptions in cancer screening, diagnosis, and treatment observed worldwide, increasing attention has focused on whether SARS‐CoV‐2 ...
