Scientific Name: Mus musculus Species: Mouse Strain: C57BL/6J

Description
OBJECTIVE:
The spaceflight environment influences immune cell distribution, ex vivo responses to antigen, and cytokine expression. However, few studies have characterized the impact of the spaceflight environment on the host immune response following an in vivo immune challenge, particularly those involving B cells and antibody production. The International Space Station (ISS) provides an ideal laboratory within which investigators can explore this unique environment and its impact on the host response. Through the use of a mouse model (with an immune system that closely parallels that of humans), we will establish a link between exposure to the spaceflight environment and decrements in immune system activation. This study is significant because it will directly test the hypothesis that host immunological health will be compromised in space.
