Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once ...
