Restraint of Powassan virus replication by TRIM5α facilitates viral avoidance of antiviral immunity

This study reveals that primate TRIM5α proteins restrict most tick-borne orthoflaviviruses but fail to inhibit Powassan virus due to a specific NS3 mutation that enables high replication, ultimately demonstrating that TRIM5α-mediated restraint of viral replication serves as a mechanism to avoid triggering strong early innate immune responses.

Integrated in vivo and transcriptomic analyses of lethal Oropouche virus infection reveal suppression of pathogenic host responses by antiviral therapy

This study demonstrates that the antiviral drug favipiravir completely protects against lethal Oropouche virus infection in a hamster model by suppressing viral replication and preventing fatal neuroinvasion, while transcriptomic analysis reveals that effective treatment abrogates the virus-induced inflammatory and metabolic disruptions responsible for pathogenesis.

Age-dependent pathogenicity of two severe fever with thrombocytopenia syndrome viruses in a ferret model

This study establishes that host age is the primary determinant of disease severity in ferrets infected with two distinct genotypes of Severe Fever with Thrombocytopenia Syndrome virus (SFTSV), with older animals exhibiting rapid, lethal progression compared to the milder, delayed symptoms in younger ferrets, thereby validating an age-stratified ferret model for evaluating SFTSV countermeasures.

Symbiosis reshapes the metabolism of sulfate-reducing bacteria in gutless marine worms

This study reveals that symbiotic sulfate-reducing bacteria in gutless marine worms have evolved a distinct, oxygen-tolerant metabolic profile characterized by the retention of core functions, the loss of nutrient-scavenging mechanisms, and the expression of the glyoxylate bypass, resulting in larger genomes that support metabolic versatility within their host-associated environment.
