Cerebral ischemia-reperfusion
WebCerebral ischemia-reperfusion (I-R) is a complex pathological process. Although autophagy can be evoked by ischemia, its involvement in the reperfusion phase after ischemia and its contribution to the fate of neurons remains largely unknown. WebMay 4, 2024 · This phenomenon, called cerebral ischemia/reperfusion injury (CIRI) ( Sun et al., 2024 ), occurs because although oxygen levels are restored to normal after reperfusion, reactive oxygen species (ROS) are produced during this process, and infiltration of proinflammatory neutrophils into ischemic tissues aggravates ischemic …
