Rapamycin
mTOR inhibitor - Autophagy Inducer
Rapamycin is an inhibitor of the Ser/Thr protein kinase named "mammalian target of rapamycin" (mTOR) that regulates cell growth and metabolism in response to environmental cues.
Rapamycin is also an inducer of autophagy, as inhibition of mTOR mimics cellular starvation by blocking signals required for cell growth and proliferation [2]. mTOR is a downstream target of PI3K, an important actor in TLR signaling [1]. Moreover, Rapamycin can block TLR2- and TLR4-mediated expression of TNF-α and IL-6 in neutrophils stimulated with Pam3CSK4 or LPS [3].
Working concentration:
- 10-100 nM when used as an inhibitor in the TLR signaling cascade
- 10-500 nM when used to induce autophagy
