Abstract
Ischemic stroke is one of the major causes of neurological morbidity and mortality in the world. Although the management of ischemic stroke has been improved significantly, it still imposes a huge burden on the health and property. The integrity of the neurovascular unit (NVU) is closely related with the prognosis of ischemic stroke. Growing evidence has shown that semaphorins, a family of axon guidance cues, play a pivotal role in multiple pathophysiological processes in NVU after ischemia, such as regulating the immune system, angiogenesis, and neuroprotection. Modulating the NVU function via semaphorin signaling has a potential to develop a novel therapeutic strategy for ischemic stroke. We, therefore, review recent progresses on the role of semphorin family members in neurons, glial cells and vasculature after ischemic stroke.
Highlights
Ischemic stroke is one of the leading causes resulting in high mortality and substantial loss of neurological function in the world (Tsai et al, 2013)
Regulation of the neurovascular unit (NVU) in multiple ways promotes the rehabilitation of neurological function, such as maintaining blood-brain barrier (BBB) integrity and regulating glial cell activity
In central nervous systems (CNS), semaphorins have been shown to be involved in many diseases, and several semaphorin members have been reported to participate in Semaphorins and Ischemic Stroke pathogenic process of ischemic stroke (Sawano et al, 2015; You et al, 2019; MacKeigan et al, 2020)
