Increased tau phosphorylation and cleavage in mouse models of type 1 and type 2 diabetes.

ABSTRACT: As the population of the United States ages, the incidence of age-related neurodegenerative and systemic diseases including Alzheimer's disease (AD) and diabetes is increasing rapidly. Multiple studies report that patients with diabetes have a 50-75% increased risk of developing AD compared with age- and gender-matched patients without diabetes. Abnormally phosphorylated tau is a major building block of neurofibrillary tangles, a classic neuropathological characteristic of AD. In addition, proteolytic tau cleavage promotes AD progression due to cleaved tau serving as a nucleation center for the pathological assembly of tau filaments. The current study examines tau modification in type 1 (streptozotocin-injected) and type 2 (db/db) mouse models of diabetes. Tau phosphorylation is increased
