The mechanistic target of rapamycin (mTOR) is a master regulator of the inflammatory response in immune and non-immune cells. In immune cells mTOR regulates metabolism to fuel cell fate decision, proliferation and effector functions. In non-immune cells, such as fibroblast, it controls inflammation-associated proliferation and migration/invasion, shapes the expression of cytokines and chemokines and promotes extracellular matrix remodeling and fibrosis. Hence, mTOR plays a critical role in chronic inflammation, where a continuous feedback between stromal cells and infiltrating immune cells result in tissue remodeling and organ damage. Activation of mTOR has been implicated in a number of chronic inflammatory diseases, especially rheumatic diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), systemic sclerosis (SSc), sjogren syndrome (SS) and seronegative spondyloarthropathy (SpA). Here we review recent advances in our understanding of the mechanism of mTOR activation in inflammation, especially in rheumatic diseases. We further discuss recent findings regarding the beneficial and side effects of mTOR inhibition in rheumatic conditions.
