TRIM7 ubiquitinates SARS-CoV-2 membrane protein to limit apoptosis and viral replication.

SARS-CoV-2 is a highly transmissible virus that causes COVID-19 disease. Mechanisms of viral pathogenesis include excessive inflammation and viral-induced cell death, resulting in tissue damage. Here we show that the host E3-ubiquitin ligase TRIM7 acts as an inhibitor of apoptosis and SARS-CoV-2 replication via ubiquitination of the viral membrane (M) protein.

Efficacy of Polyphenylene Carboxymethylene (PPCM) Gel at Protecting Type I Interferon Receptors Knockout Mice from Intravaginal Ebola Virus Challenge.

Ebola virus (EBOV) is one of three filovirus members of the genus that can cause severe Ebola disease (EBOD) in humans. Transmission predominantly occurs from spillover events from wildlife but has also happened between humans with infected bodily fluids. Specifically, the sexual route through infectious male survivors could be the origin of flare up events leading to the deaths of multiple women.

Comparative thermo- and piezostability study of photosynthetic core complexes containing bacteriochlorophyll a or b.

The resilience of biological systems to fluctuating environmental conditions is a crucial evolutionary advantage. In this study, we examine the thermo- and piezo-stability of the LH1-RC pigment-protein complex, the simplest photosynthetic unit, in three species of phototropic purple bacteria, each containing only this core complex. Among these species, Blastochloris viridis and Blastochloris tepida utilize bacteriochlorophyll b as the main light-harvesting pigment, while Rhodospirillum rubrum relies on bacteriochlorophyll a.

Tetracistronic minigenomes elucidate a functional promoter for Ghana virus and unveils Cedar virus replicase promiscuity for all henipaviruses.

Unlabelled: Batborne henipaviruses, such as Nipah and Hendra viruses, represent a major threat to global health due to their propensity for spillover, severe pathogenicity, and high mortality rate in human hosts. Coupled with the absence of approved vaccines or therapeutics, work with the prototypical species and uncharacterized, emergent species is restricted to high biocontainment facilities. There is a scarcity of such specialized spaces for research, and often, the scope and capacity of research, which can be conducted at BSL-4, is limited.
