New study highlights first infection of human cells during spaceflight

(Arizona State University) In the first study of its kind, Cheryl Nickerson, lead author Jennifer Barrila and their colleagues describe the infection of human cells by the intestinal pathogen Salmonella Typhimurium during spaceflight. They show how the microgravity environment of spaceflight changes the molecular profile of human intestinal cells and how these expression patterns are further changed in response to infection. In another first, the researchers were also able to detect molecular changes in the bacterial pathogen while inside the infected host cells.
