Moreover, increased CSF levels of endothelial/pericyte markers (such as vascular endothelial growth factor (VEGF)[4], soluble platelet-derived growth factor receptor-β (sPDGFRβ) [5] as well as markers for BBB disruption (Q-albumin [6, 7] and fibrinogen [8])) have been seen in AD patients. Here, VEGFA is linked to Alzheimer disease.
