PET is becoming intensively used for the detection of early stages of AD by the visualisation of Abeta accumulation within the brain. However, since accumulations have already occurred and Abeta removing therapies are still not available the need for tools that aid early diagnosis or even allow risk assessment are in desperate need.
We have discovered that the ABC transporters ABCC1 and ABCB1 are major export pumps for toxic peptides from the brain via the blood-brain barrier (BBB) and the blood-choroid plexus barriers (BCPB). It is known that the function of these barriers depend on vascular integrity, age, individual medication, and diets. We investigate the use of Positron-Emission Tomography (PET) for the detection of (early) functional abrogation of the BBB and BCPB that occur before onset of disease symptoms together with our project partners from Austria.
