Intramural periarterial drainage pathway
Web <p>Amyloid β (Aβ) is produced in the neurons and transported into the vessel walls and perivascular space through the extracellular space. These pathways are designated as intramural periarterial drainage (IPAD) pathway or glymphatic system in the brain. Overproduction of Aβ or alternatively, stagnation of Aβ transportation may lead to …WebThe cognitive decline correlates with the accumulation of amyloid-β (Aβ) in the walls of capillaries and arteries. Our group has demonstrated that interstitial fluid and Aβ are …
