Tackling Immune System Dysfunction— from Multiple Angles

HOUSTON (NASA PR) — Getting sick is no fun for anyone, but it especially taxes crew members aboard the ISS. Protecting crew health is important as NASA prepares for long-duration, deep-space missions. The human immune system is a complex web of biological structures and processes; decreased activity in one piece of it can change overall disease risk. Studies have shown microgravity causes modifications in the human immune system. Figuring out why and how this occurs could help not only astronauts, but people affected by immune dysfunction here on Earth.
