IL17A and ischemic stroke: In this study, the enhanced autophagy was observed in peri-infarct region of mice after 1 h MCAO/R 24 h; and according to our previous report that IL-17A was elevated in brain homogenates and CSF after 1 h MCAO/R 12 h (5), the role of IL-17A on neuronal autophagy was further explored after ischemic stroke.
