Rapamune is an immune suppressing drug used in preventing the rejection of kidney transplants. It inhibits activation of T cells and B cells by reducing the production of IL-2 by suppressing the mTor pathway. From the comments section of a Health Rising article This is counterintuitive to the latest research. Perhaps Rapamune's immune suppressing effect outweighs its mTor inhibition. Also this is the same drug that a doctor used to cure himself of Castleman's disease. Has anyone ever tried Rapamumr or have any ideas on what this might mean?
