The effect of RVG-SCMH1-Evs treatment on photothrombotic (PT) stroke mice

Metabolic dysfunction is considered a key event after ischemic stroke. However, the underlying mechanisms of metabolic disorders in cerebral ischemia is unknown. Circular RNA SCMH1 (circSCMH1), a circular RNA that has been reported to function in brain repair after stroke, was confirmed to be involved in metabolic disorders. circSCMH1 was delivered by rabies virus glycoprotein (RVG)-modified sxtracellular vesicle. Mechanistically, circSCMH1 decreased kynurenine 3-monooxygenase (KMO) expression, a key enzyme in kynurenine metabolism. Our findings suggested that circSCMH1 inhibited KMO expression, providing insight into the mechanism by which circSCMH1 promotes stroke recovery. Overall design: To investigate the mechanism of circular RNA SCMH1 in functional recovery of photothrombotic (PT) stroke mice.
