Abstract
Type 2 diabetes mellitus (T2DM) is a risk factor for Alzheimer's Disease (AD). However,
the detailed mechanism underlying T2DM-related AD remains unknown. In DM, many types
of advanced glycation end-products (AGEs) are formed and accumulated. In our previous study,
we demonstrated that Glyceraldehyde (GA)-derived Toxic Advanced Glycation End-products
(Toxic AGEs, TAGE) strongly showed cytotoxicity against neurons and induced similar alterations
to those observed in AD. Further, GA induced dysfunctional neurite outgrowth via TAGE-β--
tubulin aggregation, which resulted in the TAGE-dependent abnormal aggregation of β-tubulin
and tau phosphorylation. Herein, we provide a perspective on the possibility that T2DM increases
the probability of AD onset and accelerates its progression.

Novel tau biomarkers phosphorylated at T181, T217 or T231 rise in the initial stages of the preclinical Alzheimer’s
continuum when only subtle changes in Aβ pathology are detected.
