2019-09-25 · The principal mechanism of action of rapamycin is the inhibition of the cellular nutrient sensor and growth regulator mTOR. In elderly humans, weekly dosing of an mTOR inhibitor (not rapamycin) increased immune function as measured by response to a flu vaccine. (Ref.) Rapamycinbelongs to the class of macrocyclic immunosuppressive drugs that are bioactive only when bound to immunophilins. Cyclosporin A and FK506, two other members of this class, selectively block the transcriptional activation of several cytokine genes, thereby inhibiting cytokine production. Sirolimus (rapamycin) is a macrocyclic triene antibiotic that is produced by fermentation of Streptomyces hygroscopicus. Sirolimus was discovered from a soil sample collected in Rapa Nui, which is also known as Easter Island [ 1 ].

Rapamycin mechanism of action

Rapamycin binds to the immunophilin FK506-binding protein 12 (FKBP12) to form a complex that binds to and inhibits the serine/threonine kinase mammalian target of rapamycin (mTOR) . Concomitant use of rapamycin and rosiglitazone delays the progression of polycystic kidney disease in Han:SPRD rats: a study of the mechanism of action Chunyan Liu,* Hongdong Li,* Xiang Gao,* Ming Yang, Li Yuan, Lili Fu, Xueqi Wang, and Changlin Mei In this video, we discuss the Mechanism of action of Immunosuppressants such as Cyclosporin, Tacrolimus, and Sirolimus.

It acts specifically on FK-binding protein 12 (FKBP12), a substance commonly referred to as an immunophilin because it binds to immunosuppressive drugs. The mammalian target of rapamycin (mTOR) signaling pathway is a master regulator of cell growth and metabolism. Deregulation of the mTOR pathway has been implicated in a number of human diseases such as cancer, diabetes, obesity, neurological diseases, and genetic disorders. The principal mechanism of action of rapamycin is the inhibition of the cellular nutrient sensor and growth regulator mTOR. In elderly humans, weekly dosing of an mTOR inhibitor (not rapamycin) increased immune function as measured by response to a flu vaccine.
