Mice display altered immune system following spaceflight
(PHYSorg.com Space & Earth)

New research published in The FASEB Journal brings to light new information regarding the increased susceptibility of mice to infection during spaceflight. Based on examinations of mice that had been on board the Bion-M1 biosatellite, the study demonstrates that the outer space environment impairs the production of B lymphocytes, the white blood cells responsible for antibody production. The study also shows that such adverse effects persist at least one week after returning to Earth.
