This study identifies the Man-PTS as a receptor for Angicin in streptococci and defines structural features associated with its antimicrobial activity.

The paper deletes four proviruses in Haloferax volcanii and finds increased motility, stress resistance, and altered CRISPR RNA expression.

This study investigates the cellular response to poxvirus infection, showing that MVA activates innate immune genes, while Camelpoxvirus activates NF-kB signaling, and poxviruses induce nuclear remodeling by transporting nuclear proteins into viral factories.

This study compares the effects of SARS-CoV-2 early strains and Omicron variants on intestinal barrier function using a human gut epithelial model, finding Omicron causes less damage.

This study identifies ARF1 as a negative regulator of cGAS-STING signaling, showing it prevents type I IFN induction by regulating STING activation and recycling.
