Popis: Type 2 diabetes (T2D) is an important risk factor to suffer dementia, being Alzheimer's disease (AD) as the most common form. Both AD and T2D are closely related to aging and with a growing elderly population it might be of relevance to explore new therapeutic approaches that may slow or prevent central complications associated with metabolic disorders. Therefore, we propose the use of the antidiabetic polypill (PP), a pharmacological cocktail, commonly used by T2D patients that include metformin, aspirin, simvastatin, and an angiotensin-converting enzyme inhibitor. In order to test the effects of PP at the central level, we have long-term treated a new mixed model of AD-T2D, the APP/PS1xdb/db mouse. We have analyzed AD pathological features and the underlying specific characteristics that relate AD and T2D. As expected, metabolic alterations were ameliorated after PP treatment in diabetic mice, supporting a role for PP in maintaining pancreatic activity. At central level, PP reduced T2D-associated brain atrophy, showing both neuronal and synaptic preservation. Tau and amyloid pathologies were also reduced after PP treatment. Furthermore, we observed a reduction of spontaneous central bleeding and inflammation after PP treatment in diabetic mice. As consequence, learning and memory processes were improved after PP treatment in AD, T2D, and AD-T2D mice. Our data provide the basis to further analyze the role of PP, as an alternative or adjuvant, to slow down or delay the central complications associated with T2D and AD.
