Intercellular Interactions in Space Flight (Mezhkletochnoe Vzaimodeistvie) - 08.05.15
Information Pending Science Results for Everyone
Because there’s no time for sick days in space, much research on the space station concerns immune system function. Previous studies have found that, in isolated cultures of mononuclear cells, communication is disrupted between T-cells (a type of white blood cell formed in the thymus gland that defends the organism from invaders) and helper cells (so named because they help other white blood cells mature or activate). This disruption inhibits T-cell activity and, therefore, immune response. But this investigation showed that microgravity is not the culprit, as it did not disturb function of cultured immune cells during 24-hour incubation with specific targets. Experiment Details
