[Human immunity system status during 7-day dry immersion].

Aerospace and Environmental Medicine 43(5):36 (2009) PMID 20120915

Subpopulations of lymphocytes, activation potential of T-, B- and NK-cells as well as cytokines production by immunocompetent cells in peripheral blood were studied in five volunteers for 7-day dry immersion without use of countermeasures. Results of the investigation revealed several negative shifts in the immunity and cytokines systems instigated by the experimental conditions. The considerable variability of the immune reactions to immersion suggests individual predisposition to immunological breaks in a changed gravity environment.
