Abstract
ABSTRACT Introduction Ischemic stroke is a life-threatening condition worldwide, including China. Nowadays, intravenous thrombolysis and mechanical thrombectomy are chiefly applied as clinical therapeutics; however, strict time windows and underlying risks limit their benefits for patients. Thus, it is urgently needed to seek new effective targets for stroke to improve clinical outcomes. Areas covered Circular RNAs have recently emerged as ideal therapeutic candidates for ischemic stroke with high stability and evolutionary conservation in the brain tissue. The neurovascular unit is a microscopic and complex three-dimensional domain key in the processes of this disease, and reflects diverse structures and functions of the brain tissue. During the progression of ischemic stroke, circular RNAs are extensively involved in the responses of the neurovascular unit including atherosclerosis, neuroinflammation, apoptosis, and neurogenesis. Additionally, they display diagnostic, monitoring, therapeutic, and prognostic effects in the occurrence of and recovery from the disease. Expert opinion Exploration of circular RNAs and their correlated effects in ischemic stroke may facilitate accurate diagnosis and serve as new therapeutic targets for the disease.
