MicroRNA (miRNA) and the immune system

During the last few years, several types of small regulatory RNA-sRNA have been described, which participate in gene silencing. So far, the largest group of sRNA described is microRNA, which are multifunctional molecules that participate in many physiological and pathological processes in mammals. As it turns out, the molecules are also related to the immune system, and their participation was described in both innate and adaptive immunity.
