Antigen-Specific CD4+ T Cell Priming and Memory Response During Spaceflight (ARC00XX19)
Principal Investigator
Research Area:
Cell and molecular biology
Species Studied
Scientific Name: Mus musculus Species: Mouse Strain: B6.SJL-Ptprca Pepcb/BoyJ


The experiment tested whether initial specific activation of T cells is intact and whether memory T cell function is maintained during space flight to determine resistance to infections and acquired immune responses.
