European Space Agency (ESA) astronaut Thomas Reiter performed the experiments while on the ISS, as seen in the video below. Human immune cells were allowed to float freely in microgravity while others were placed in a centrifuge that simulated gravity. The cells in the centrifuge were found to be more healthy than those left to float.[ emphasis added]

Yesterday, I saw on Quora that the human immune system doesn't work properly in weightlessness of space. That seemed like terrible news. But the above quote shows that artificial gravity may lessen or even reverse that outcome, which is quite reassuring. For if the immune system is irreversibly compromised, human space travel becomes problematic. Let's hope that this is not the conclusion and that artificial gravity will enable people to live in space indefinitely.
