microRNA(miRNA)是调节生物体发育的有效分子,表现为对基因的微量调节。现有的证据表明miRNA参与天然免疫和适应性免疫应答的调节,这种调节与免疫系统发挥作用有十分密切的关系。因此,对miRNA的研究有助于对人类免疫系统调节机制更深入地了解,建立基于miRNA的有效疗法。 MicroRNAs (miRNAs) are effective molecules that regulate the development of the organism and appear to be micro-regulation of genes. Available evidence suggests that miRNAs are involved in the regulation of innate and adaptive immune responses that are closely related to the role of the immune system. Therefore, the study of miRNA helps to better understand the regulation mechanism of human immune system and establish effective miRNA-based therapy.
