Regulatory T cells: MicroRNAs maintain identity.

The article reports on the research on microRNAs in the U.S. The research revealed that microRNAs are needed to safeguard the function of regulatory T cells, and are required to maintain T cells activity, which befit their suggested role in buffering gene expression in conditions of environmental stress. It is concluded that this study highlights an essential role for microRNA-dependent regulation of gene expression in the maintenance of T cells homeostasis and suppressive function.
