While, for example, pFTAA, an anionic pentameric oligothiophene, binds to several different types of amyloid aggregates (including Aβ, p-tau, and prions) [22, 24–26], the recently developed ligand bTVBT2 appears to specifically bind to aggregated tau pathologies, and not Aβ, found in human AD brain tissue Sects. [27]. Here, MAPT is linked to Alzheimer disease.
