Mars, Amphibians, and Astronaut Antibodies
The trip to Mars just got a little more difficult now that French researchers have discovered that antibodies used to fight off disease might become seriously compromised during long-term space flight. In a new report published online in the FASEB Journal, the scientists show that antibodies produced in space are less effective than those produced on terra firma. The reduced effectiveness of antibodies makes astronauts more susceptible to illness, while increasing the danger posed by bacteria and viruses likely to coexist with wayfaring astronauts.
“We hope to find efficient pharmacological and/or nutritional countermeasures to alterations of the immune system that could be useful to astronauts and to people who have weak immune systems on Earth because of infections, aging, or chronic stress exposure,” said Jean-Pol Frippiat, a researcher involved in the work from the Faculty of Medicine, Development and Immunogenetics at the Université Henri Poincaré-Nancy, Vandœuvre-lès-Nancy, France.
