Inoculation of sarkosyl-insoluble fractions of brain homogenates from human tauopathies, including AD, primary age-related tauopathy (PART), aging-related tau astrogliopathy (ARTAG), PSP, AGD, Pick’s disease (PiD), frontotemporal lobar degeneration linked to MAPT P301L mutation, and globular glial tauopathy (GGT) reproduces a tauopathy, but inoculated mice do not express the markers of specific tauopathies [22,23,24,25,26]. Here, MAPT is linked to argyrophilic grain disease.
