The emerging role of miRNA in regulating the mTOR signaling pathway in immune and inflammatory responses.

Immunol Cell Biol 2021 May 14. Epub 2021 May 14.

Cellular and Molecular Research Center, Yasuj University of Medical Sciences, Yasuj, Iran.

The mechanistic/mammalian target of rapamycin (mTOR) is considered to be an atypical protein kinase that plays a critical role in integrating different cellular and environmental inputs in the form of growth factors, nutrients, and energy and, subsequently, in regulating different cellular events, including cell metabolism, survival, homeostasis, growth, and cellular differentiation. Immunologically, mTOR is a critical regulator of immune function through integrating numerous signals from the immune microenvironment, which coordinates the functions of immune cells and T cell fate decisions. The crucial role of mTOR in immune responses has been lately even more appreciated. Read More
