Progress of researches on the mechanisms of acupuncture intervention underlying improvement of ischemic stroke by regulating microRNAs.

MicroRNAs play an important role in the occurrence and development of ischemic stroke (IS). A lot of researches have shown that acupuncture intervention can improve IS-induced neural dysfunction by regulating miRNA. In the present paper, we summarized the current progress of researches on the mechanisms of acupuncture underlying improvement of IS via regulation of miRNA from 1) promoting angiogenesis and increasing cerebral blood flow, 2) inhibiting inflammatory response, 3) maintaining blood-brain barrier homeostasis and relieving brain edema, 4) regulating programmed cell death, 5) promoting neuron regeneration, and 6) improving synaptic plasticity. These miRNA -related mechanisms may provide a reference for the follow-up research .
