Millie Hughes-Fulford, Scientist and Prior Astronaut

CAPE CANAVERAL, Fla. - Researcher and former NASA payload specialist Millie Hughes-Fulford, of the Hughes-Fulford Laboratory, San Francisco, Calif., discusses her laboratory's T-cell experiment and the impact the research may have on aging adults and their immune systems with an interviewer in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. The immunology experiment will launch on SpaceX-3 and focus on the effects of microgravity on early T-cell signaling pathways. Current work aims to identify and compare the gene expression of microRNAs miRNAs during T-cell activation under normal gravity and in microgravity, and compare those patterns to changes seen in aging populations. The experiment will be the first flown on SpaceX funded by the National Institutes of Health. Dr. Hughes-Fulford flew aboard space shuttle mission STS-40 in June 1991, the first Spacelab mission dedicated to biomedical studies.
