In addition to cerebral ischemia, many findings have also confirmed that in other neurodegenerative disorders (such as Alzheimer’s disease and Parkinson’s disease), cerebrospinal fluid (CSF) FABP3 levels [47,48] and serum FABP7 levels [49] are elevated in patients, and FABP5 is upregulated in a mouse model of Alzheimer’s disease [50]. The gene discussed is FABP3; the disease is early-onset autosomal dominant Alzheimer disease.
