To explore the effects of T294-HBc VLP vaccine on the animal models of FTD and AD, we applied the vaccine to the Tau.P301S transgenic mouse model, which is widely used to mimic the incidence and progression of FTD and AD and recapitulates the essential molecular and cellular features of the human tauopathies, including truncated tau generation, hyperphosphorylation, tau filament formation, and neurodegeneration [31, 39]. Here, MAPT is linked to frontotemporal dementia.
