After just five days, she observed the ears of mice lacking mast cells were surprisingly thicker than had been the ears of regular mice, suggesting a build up of white blood cells. By injecting mast cells back to the deficient mice, Grimbaldeston discovered the immune-suppressing molecule the cells secrete to limit ear canal swelling: interleukin-10. She also determined which antibodies activated the mast cell receptors to trigger IL-10's release. Trial injections of IL-10 have reduced inflammation in patients experiencing rheumatoid arthritis and psoriasis, with mixed results. However given the manufacturing price of producing IL-10, Galli thinks it an unlikely useful treatment for poison oak or sun exposure.The U.S. Military, all by itself, gets the know-how to engineer and unleash such a virus. That doesn’t mean they’ve carried out so, however. It might be an astonishing leap into crimes against humanity to intentionally unleash such a biological weapon into the wild. Then once again, governments of the globe have routinely involved in crimes against humanity, haven’t they? The U.S., for instance, dropped nuclear bombs on civilian populations in Japan. Israel rained white phosphorous on Palestinians, Hitler exterminated countless Jews, and Us citizens fired an incredible number of rounds of depleted uranium rounds into targets in Iraq and Afghanistan.
