Abstract
Since the mid-1990s, scientists have been generating mouse models of Alzheimer's disease to elucidate key mechanisms underlying the onset and progression of the disease and aid in developing potential therapeutic approaches. The first successful mouse model of Alzheimer's disease was reported in 1995 with the generation of the PDAPP mice, which were obtained by the overexpression of gene coding for the amyloid precursor protein (APP). Since then, scientists have used different approaches to develop other APP overexpression mice, mice overexpressing tau, or a combination of them. More recently, Saito and colleagues generated a mouse model by knocking in mutations associated with familial Alzheimer's disease into the APP gene. In this review, we will describe the most used animal models and provide a practical guide for the disease's age of onset and progression. We believe that this guide will be valuable for the planning and experimental design of studies utilizing these mouse models.
