Message in a bottle: Info-rich bubbles respond to antibiotics
Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were produced and released by bacteria in greater abundance and traveled faster and further from their origin. The work sheds new light on these important information-carrying entities, implicated in many cellular communication processes, including antibiotic resistance.
