Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Coronavirus Nsp3 Hijacks CLTC to Modulate Autophagosome Nucleation for Promoting DMV Formation and Viral Replication

Advanced Science, Volume 13, Issue 24, 27 April 2026.
In wild‐type cells, FIPV infection recruits CLTC to nsp3, facilitates DMV biogenesis and block autophagic flux to promote viral replication. CLTC knockout impairs autophagosome nucleation by reducing Beclin1–ATG14 complex expression. This disrupts the formation of autophagic precursor membranes, thereby preventing their hijacking by nsp3 for DMV ...

Tubercidin inhibits PRRSV replication via RIG-I/NF-κB pathways and interrupting viral nsp2 synthesis

Microbiology Spectrum
Porcine reproductive and respiratory syndrome virus (PRRSV) is an RNA virus with constantly emerging recombinant and mutant strains. Because of the high genetic diversity of PRRSV, current vaccines only provide partial protection against the infection of

Viroplasms: Assembly and Functions of Rotavirus Replication Factories

Viruses, 2021
Viroplasms are cytoplasmic, membraneless structures assembled in rotavirus (RV)-infected cells, which are intricately involved in viral replication. Two virus-encoded, non-structural proteins, NSP2 and NSP5, are the main drivers of viroplasm formation ...

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.

The full-length nsp2 replicase contributes to viral assembly in highly pathogenic PRRSV-2

Journal of Virology
Porcine reproductive and respiratory syndrome viruses (PRRSVs) are significant pathogens that affect the global swine industry. Its virions consist of a central core composed of nucleocapsid (N) protein, surrounded by multiple distinct viral envelope ...

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 ...

Serological responses to rotavirus NSP2 following administration of RV3-BB human neonatal rotavirus vaccine

Human Vaccines & Immunotherapeutics, 2018
Serum rotavirus IgA responses are an imperfect non-mechanistic correlate of protection, and the lack of an accurate serological marker is a challenge to the development of new rotavirus vaccines.

Protein-mediated RNA folding governs sequence-specific interactions between rotavirus genome segments [PDF]

, 2017
Segmented RNA viruses are ubiquitous pathogens, which include influenza viruses and rotaviruses. A major challenge in understanding their assembly is the combinatorial problem of a non-random selection of a full genomic set of distinct RNAs. This process

Diverse Scaffolds Facilitate NLRP3 Clustering and Inflammasome Formation in Response to Perturbations in Cell Homeostasis

BioEssays, Volume 48, Issue 3, March 2026.
NLRP3, a cytosolic innate immune sensor, responds to diverse activators that perturb cellular homeostasis. These disturbances generate molecular scaffolds that, through binding partners such as nucleic acids, lipids, and proteins, recruit and concentrate NLRP3. Scaffold‐mediated NLRP3 clustering promotes NLRP3 inflammasome assembly.
