Palmitoylethanolamide protects blood-brain-barrier in stroke

In an experimental model palmitoylethanolamide and related molecules could protect the brain against ischemic insults such as stroke, by decreasing the permeability of the blood-brain-barrier (BBB). Application of palmitoylethanolamide at 10 μM decreased the insult-induced increase in BBB permeability during reperfusion after stroke.

The conclusion of the authors was that compounds such as palmitoylethanolamide:

“may play an important modulatory role in normal BBB physiology, and also afford protection to the BBB during ischaemic stroke, through a number of target sites.”

From many other studies it was already quite clear, that PEA protects cells and tissues against all kinds of damage, from UV light up to ischemia.
