An international team led by the University if Barcelona has identified a new antibacterial mechanism that protects macrophages from infection by the bacteria Salmonella enterica serovar Typhimurium, a pathogen associated with several gastrointestinal diseases. This discovery, carried out with mice and published in the journal Cell Reports, is led by Professor Annabel Valledor, from the Faculty of Biology of the University of Barcelona, and could open new exploration channels for pharmacological treatments of some bacterial infections.
