Could leaky blood vessels in the brain be a culprit in Alzheimer's disease?

Researchers report that they found high levels of the protein Fli-1 in the brains of deceased Alzheimer's patients. Blocking Fli-1's action in a mouse model of Alzheimer's disease reversed mental loss and reduced the brain inflammation and amyloid-beta clumping that are hallmarks of Alzheimer's disease. Although clinical translation of this finding is likely years off, the study suggests Fli-1 is a promising therapeutic target for Alzheimer's disease.
