It has been well recognized that BDNF is the most abundant endogenous neurotrophic factor in the body, and reduced levels of BDNF were reported to play a key role in rodent models during the development of neurological disorders, such as cerebral ischemia‐reperfusion injury2 and neuroinflammation‐related brain injury.3 The gene discussed is BDNF; the disease is Cerebral ischemia.
