Missing link found between brain and immune system

In a discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist.

Fighting Fit For Space Travel




The suppression of the human immune system in space was first observed forty years ago during the Apollo missions when more than half the astronauts reported a bacterial or viral infection either during or shortly after their mission. To further study the effects of micro-gravity on the immune system, a shuttle flight in 1991 carried […]
