Sirtuins are NAD+-dependent enzymes that regulate a large number of cellular pathways and are related to aging and age-associated diseases. In recent years, the role of sirtuins in Alzheimer's disease (AD) has become increasingly apparent. Growing evidence demonstrates that sirtuin 1 (SIRT1) regulates many processes that go amiss in AD, such as: APP processing, neuroinflammation, neurodegeneration, and mitochondrial dysfunction. Here we review how SIRT1 affects AD and cognition, the main mechanisms in which SIRT1 is related to AD pathology, and its importance for the prevention and possible diagnosis of AD.
Keywords: Alzheimer's disease; Cognition; Neurodegeneration; SIRT1; Sirtuins.
