Mild hypothermia therapy attenuates early BBB leakage in acute ischemic stroke.

ABSTRACT: Reperfusion therapy inevitably leads to brain-blood barrier (BBB) disruption and promotes damage despite its benefits for acute ischaemic stroke (AIS). An effective brain cytoprotective treatment is still needed as an adjunct to reperfusion therapy. Here, we explore the potential benefits of therapeutic hypothermia (HT) in attenuating early BBB leakage and improving neurological outcomes. Mild HT was induced during the early and peri-recanalization stages in a mouse model of transient middle cerebral artery occlusion and reperfusion (tMCAO/R). The results showed that mild HT attenuated early BBB leakage in AIS, decreased the infarction volume, and improved functional outcomes. RNA sequencing data of the microvessels indicated that HT decreased the transcription of the actin polymerization-
