AI Article Synopsis

  • Successful replication of the influenza A virus relies on both viral proteins and host cellular factors, prompting a search for small molecules that can disrupt these components.
  • The researchers utilized a reporter assay to screen a chemical compound library, leading to the discovery of compound 7, which inhibits a new target related to viral replication.
  • Compound 7 demonstrated dose-dependent efficacy in reducing viral replication in lab studies and proved effective in overcoming high-dose influenza infection in a mouse model, suggesting potential for developing new anti-influenza treatments amid rising oseltamivir resistance.

Article Abstract

Successful replication of the influenza A virus requires both viral proteins and host cellular factors. In this study we used a cellular assay to screen for small molecules capable of interfering with any of such necessary viral or cellular components. We used an established reporter assay to assess influenza viral replication by monitoring the activity of co-expressed luciferase. We screened a diverse chemical compound library, resulting in the identification of compound 7, which inhibits a novel yet elusive target. Quantitative real-time PCR studies confirmed the dose-dependent inhibitory activity of compound 7 in a viral replication assay. Furthermore, we showed that compound 7 is effective in rescuing high-dose influenza infection in an in vivo mouse model. As oseltamivir-resistant influenza strains emerge, compound 7 could be further investigated as a new and potentially suitable scaffold for the development of anti-influenza agents that act on novel targets.

Because of high mutation rates, viruses constantly adapt to new environments. When propagated in cell lines, certain viruses acquire positively charged amino acids on their surface proteins, enabling them to utilize negatively charged heparan sulfate (HS) as an attachment receptor. In this study, we used enterovirus A71 (EV-A71) as model and demonstrated that unlike the parental MP4 variant, the cell-adapted strong HS-binder MP4-97R/167G does not require acidification for uncoating and releases its genome in the neutral or weakly acidic environment of early endosomes.

Rubella virus (RUBV) is responsible for causing rashes, lymphadenopathy, and fever which are the hallmarks of an acute viral illness called Rubella. For RUBV replication, the non-structural polyprotein p200 must be cleaved by the rubella papain-like protease (RubPro) into the multifunctional proteins p150 and p90. Hence, RubPro is an attractive target for anti-viral drug discovery.

Role of Vigilin and RACK1 in dengue virus- interactions.

Vigilin is a large and evolutionary conserved RNA-binding protein (RBP), which can interact with RNA through its KH domain. Vigilin is, therefore, a multifunctional protein reported to be associated with RNA transport and metabolism, sterol metabolism, chromosome segregation, carcinogenesis, and heterochromatin-mediated gene silencing. The receptor for activated C kinase 1 (RACK1) is another highly conserved protein involved in many cellular pathways.

Unlabelled: African swine fever (ASF) is a highly contagious and often lethal disease caused by African swine fever virus (ASFV) in pigs. Protein palmitoylation is a prevalent posttranslational lipid modification that can modulate viral replication. In this study, we investigated the palmitoylation of ASFV proteins.

Variability in HIV-1 transmitted/founder virus susceptibility to combined APOBEC3F and APOBEC3G host restriction.

Several APOBEC3 enzymes restrict HIV-1 by deaminating cytosine to form uracil in single-stranded proviral (-)DNA. However, HIV-1 Vif counteracts their activity by inducing their proteasomal degradation. This counteraction by Vif is incomplete, as evidenced by footprints of APOBEC3-mediated mutations within integrated proviral genomes of people living with HIV-1.
