Axonal injury and repair mechanism after ischemic stroke

The process of axonal injury after ischemic stroke can be roughly divided into three stages. Each stage has its different temporal and spatial pattern, as well as unique molecular cascade reactions. The process of axonal injury is also related to ischemic stroke subtype, and the treatment must be adjusted accordingly. Axon-glial intercellular neurotransmitter-energy metabolism coupling disorder and Ca2+ overload-mediated apoptosis-like degeneration are the main mechanisms of early axonal injury after stroke. Axonal regeneration and remyelination of damaged axons after stroke play an important role for the recovery of neurological function. Elucidating the axonal injury and repair mechanism after stroke can provide a new strategy for stroke treatment. Key words: Stroke; Brain Ischemia; Neurons; Axons; Nerve Degeneration
