Mode of action of plasmolysed yeast on lymphocytes under microgravity stress.
A newly developed device to simulate microgravity for space biological investigations under laboratory conditions allowed us to apply a reproducible environmental stress on immunologically active cells. Cell proliferation, soluble IL-2 receptor in the culture supernatant, lymphocyte surface activation markers like CD25 (IL-2R), CD69 and HLA-Dr were the endpoints measured. Untreated donor lymphocyte reactions under microgravity were compared to the same cells treated with an immunomodulator from herbal plasmolysed yeast (Bio-Strath Food Supplement). The main finding is the enhancement of the proliferation inhibition under microgravitational stress by the herbal plasmolysed yeast.
