An experiment study has indicated that rapamycin, an mTOR inhibitor, reduces Aβ, and tau pathology in the brains of 3xTg-AD mice. It was also observed that tau pathology in mice was directly linked with Aβ deposits. Thus, it is still unclear that whether rapamycin reduces tau pathology due to changes in amyloid-β or because of direct relation between mTOR and tau. Thus interpreting this relation will not only help in understanding role of mTOR in AD but also in other tau related abnormalities
