Article Abstract
Nitric oxide (NO) is a vital immune molecule eliciting resistance to diverse microbial pathogens in humans and animals. However, its functional integration into plant immune networks remains incompletely characterized. In this study, we reveal that both endogenous induction and exogenous supplementation of NO significantly enhance resistance to rice stripe virus (RSV), a Bunyavirus that poses a huge threat to rice production. The nitrate transporter OsNPF6.1 potentiates virus resistance by upregulating the expression of nitrate reductase (OsNR2) and subsequent NO biosynthesis. Functional analyses demonstrate that the disease-specific protein (SP) encoded by RSV interacts with OsNPF6.1 to impair its nitrate transport activity, effectively subverting host immunity to facilitate RSV infection. Notably, this host-pathogen interaction exhibits nitrogen dependency: low nitrate availability attenuates the OsNPF6.1-SP association, preserving transporter functionality and virus resistance. Thus, this study not only provides novel insights into the coordination of growth-defense tradeoffs but also proposes actionable strategies for crop protection via optimized nitrogen management.

Our previous work identified p3-interacting protein (P3IP) as a novel plant factor that interacts with rice stripe virus p3 protein and activates autophagy to mediate its degradation, thereby restricting infection. However, the mechanism of P3IP-mediated autophagy and the evolutionary conservation of its antiviral function remain unknown. This study demonstrates that two Arabidopsis thaliana homologs, AtP3IP and AtP3IPH (Arabidopsis P3IP homologs, AtP3IPs), similarly activate autophagy and confer resistance to turnip mosaic virus (TuMV).

Oncolytic virotherapy (OVT) has emerged as a promising and innovative cancer treatment strategy that harnesses engineered viruses to selectively infect, replicate within, and destroys malignant cells while sparing healthy tissues. Beyond direct oncolysis, oncolytic viruses (OVs) exploit tumor-specific metabolic, antiviral, and immunological vulnerabilities to reshape the tumor microenvironment (TME) and initiate systemic antitumor immunity. Despite promising results from preclinical and clinical studies, several barriers, including inefficient intratumoral virus delivery, immune clearance, and tumor heterogeneity, continue to limit the therapeutic advantages of OVT as a standalone modality and hindered its clinical success.

Punicalagin, a polyphenolic compound extracted from pomegranate peel, has received increasing attention in recent years due to its antibacterial and antiviral properties. Punicalagin is capable of inhibiting bacterial growth at sub-inhibitory concentrations by affecting cell membrane formation, disrupting membrane integrity, altering cell permeability, affecting efflux pumps, interfering with quorum sensing and influencing virulence factors. Additionally, punicalagin inhibits viruses by modulating enzyme activity, interacting with viral surface proteins, affecting gene expression, blocking viral attachment, disrupting virus receptor interaction and inhibiting viral replication.

Waterborne viruses have caused outbreaks of related diseases and threaten human health, and advanced oxidation processes (AOPs), as clean and efficient technologies, have received widespread attention for their excellent performance in inactivating viruses. However, heterogeneity in susceptibility of structurally distinct viruses to various reactive oxygen species (ROS) is unclear. This study first measured the heterogeneity in inactivation kinetics and biological mechanisms of four typical viral surrogates (MS2, phi6, phix174, and T4) to various ROS by visible light catalysis.

The role of cholesterol metabolism in antiviral immunity has been established, but if and how this cholesterol-mediated immunometabolism can be regulated by specific small molecules is of particular interest in the quest for novel antiviral therapeutics. Here, we first demonstrate that NPC1 is the key cholesterol transporter for suppressing viral replication by changing cholesterol metabolism and triggering the innate immune response via systemic analyses of all possible cholesterol transporters. We then use the Connectivity Map (CMap), a systematic methodology for identifying functional connections between genetic perturbations and drug actions, to screen NPC1 inhibitors, and found that bis-benzylisoquinoline alkaloids (BBAs) exhibit high efficacy in the inhibition of viral infections.
