HAL5 - National Space Society

Our scheduled speaker is Dr. Marian L. Lewis, Ph.D., retired Research Professor in the Department of Biological Sciences and Director of the Bioreactor and Microgravity Biotechnology Laboratory at the UAHuntsville. She will be giving a lecture on "Life in Space: A Cell's Perspective."  From an historical perspective, cell culture technology and manned spaceflight co-evolved. Both gained celebrity status in the early nineteen sixties. But use of cultured cells to investigate effects of spaceflight on living systems was not accorded credibility until 1984 when Swiss researchers reported a 90% reduction in growth response in cultured T cells in microgravity. Now, a quarter century later, we know that spaceflight elicits a number of cell-level responses. Dr. Lewis' 39 cell experiments have flown on 14 space shuttle missions. She will summarize her research, which focused on effects of spaceflight on the cytoskeleton, signal transduction, cell growth, and gene expression in human T lymphocytes (T cells). Her results indicate that the cytoskeleton may function in microgravity-related response of the immune system at the cellular level.  She will also present historical perspectives of the commercial space program and flight hardware and describe some of the cell-related mysteries that remain to be solved.  For more information, please visit &nbsp;</div><div>&nbsp;</div><div>&nbsp;</div">http://www.HAL5.org
