Space Station Live: Studying the Immune System In Space

An experiment on the International Space Station explores why astronauts' immune systems become suppressed in microgravity. NASA Public Affairs Officer Lori Meggs talks about the experiment, T-Cell Activation in Aging, with Principal Investigator and former shuttle astronaut Millie Hughes Fulford. Read more...

For an Immune Cell, Microgravity Mimics Aging

Telling someone to “act your age” is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to misbehave with age, leaving the elderly more vulnerable to illness. Because these cells are known to misbehave similarly during spaceflight, researchers are studying the effects of microgravity on immune cells to better understand how our immune systems change as we age.

Study Reveals Immune System is Dazed and Confused During Spaceflight

There is nothing like a head cold to make us feel a little dazed. We get things like colds and the flu because of changes in our immune system. Researchers have a good idea what causes immune system changes on Earth—think stress, inadequate sleep and improper nutrition. But the results of two NASA collaborative investigations-Validation of Procedures for Monitoring Crewmember Immune Function (Integrated Immune) and Clinical Nutrition Assessment of ISS Astronauts, SMO-016E (Clinical Nutrition Assessment)-recently published in the Journal of Interferon & Cytokine Research suggest that spaceflight may temporarily alter the immune system of crew members flying long duration missions aboard the International Space Station. This is of concern as NASA looks ahead to six-month and multiple-year missions to asteroids, the moon and Mars because something as simple as a cold or the flu can be risky business in space.
