MAPT and pelvic inflammatory disease: A recent study injected brain homogenates from subjects with sporadic AD, primary age-related tauopathy (PART), pure aging-related tau astrogliopathy (ARTAG), globular glial tauopathy (GGT), PSP, PiD, and frontotemporal lobar degeneration linked to P301L mutation (FTLD-P301L) into the ipsilateral corpus callosum of adult wildtype mice induced tau seeding of murine tau in the contralateral corpus callosum (Ferrer et al., 2019).
