Elevated Testosterone Level and Urine Scent Marking in Male 5xFAD Alzheimer Model Mice

Background:Function of the Amyloid Precursor Protein (AβPP) and its various cleavage products still is not unraveled down to the last detail. While its role as a source of the neurotoxic Amyloid beta (Aβ) peptides in Alzheimer’s Disease (AD) is undisputed and its property as a cell attachment protein is intriguing, while functions outside the neuronal context are scarcely investigated. This is particularly noteworthy because AβPP has a ubiquitous expression profile and its longer isoforms, AβPP750 and 770, are found in various tissues outside the brain and in non-neuronal cells.Objective:Here, we aimed at analyzing the 5xFAD Alzheimer’s disease mouse model in regard to male sexual function.…
