Lessons from tenascin-C knockout mice and potential clinical application to subarachnoid hemorrhage

摘要

Subarachnoid hemorrhage by a ruptured cerebral aneurysmremains the most devastating cerebrovascular disorderswith high morbidity and mortality (Suzuki et al.,2017), which are mainly caused by early brain injury anddelayed cerebral ischemia. Despite many experimentaland clinical research efforts, the mechanisms of earlybrain injury as well as delayed cerebral ischemia remainunclarified. However, recent works have suggested thattenascin-C, which is a special type of secreted extracellularmatrix proteins, is promising as a novel therapeutictarget against post-subarachnoid hemorrhage early braininjury and delayed cerebral ischemia.
