Summary

DescriptionImmune Figure 3.jpg	English: Figure 13-3. T cell function was elevated immediately post-flight for short-duration Shuttle crewmembers (A), but was significantly reduced post-flight for long-duration ISS crewmembers (B). Data were derived from culturing whole blood with antibodies to stimulate T cell activation for 24 hours, then assessing T cell activation marker expression (CD69 or CD25). Number of subjects to date: shuttle = 9, ISS = 6.
