Description
This study tested the hypothesis that transcription of immediate early genes is inhibited in T cells activated in microgravity (mg). Immunosuppression during spaceflight is a major barrier to safe long-term human space habitation and travel. The goals of these experiments were to prove that mg was the cause of impaired T cell activation during spaceflight as well as understand the mechanisms controlling early T cell activation. T cells from 4 human donors were stimulated with concanavalin A (ConA) and anti-CD28 onboard the International Space Station (ISS). An onboard centrifuge was used to generate a 1g simultaneous control to isolate the effects of mg from other variables of spaceflight. Microarray expression analysis after 1.5 hours of activation demonstrated that mg- and 1g-activated T cells had distinct patterns of global gene expression and identified 47 genes that were significantly differentially down-regulated in mg. Importantly, several key immediate early genes were inhibited in mg.
