    “Researchers at the San Francisco VA Medical Center have identified a set of key immune-response genes that do not turn on in a weightless environment. The discovery is another clue in the effort to solve an almost 40-year-old mystery: why the human immune system does not function well in the weightlessness of space,” from UCSF press release dated 10/12/2005 (Also on SpaceRef).
