| Stroke is the second leading cause of death and
the most common cause of adult disabilities among elderlies.
It involves a complex series of mechanisms among
which, excitotoxicity is of great importance. Also, miRNAs
appear to play role in post-stroke excitotoxicity, and
changes in their transcriptome occur right after cerebral
ischemia. Recent data indicate that specific miRNAs such
as miRNA-223, miRNA-181, miRNA-125a, miRNA-125b,
miRNA-1000, miRNA-132 and miRNA-124a regulate
glutamate neurotransmission and excitotoxicity during
stroke. However, limitations such as poor in vivo stability,
side effects and inappropriate biodistribution in miRNAbased
therapies still exist and should be overcome before
clinical application. Thence, investigation of the effect of
application of these miRNAs after the onset of ischemia is
a pivotal step for manipulating these miRNAs in clinical
use. Given this, present review concentrates on miRNAs
roles in post-ischemic stroke excitotoxicity. |
