Título: | Males vs females: differences in the AB accumulation |
Autor: | Ordóñez-Gutiérrez, Lara CSIC ORCID; Fernández, Iván; Antón Pérez, Marta; Wandosell, Francisco CSIC ORCID | Fecha de publicación: | sep-2015 | Citación: | III Congreso Internacjional de Investigación e Innovación en Enfermedades Neurodegenerativas in Málaga, Spain, 21-23 September 2015 | Resumen: | Background: The accumulation of extracellular amyloid-beta (Aß) peptide and intracellular neurofibrillary tangles in the brain are two major neuropathological hallmarks of Alzheimer's disease (AD). For the analysis of Aß-peptide aggregation, different mouse models (single or double transgenic mice) have been used to follow the evolution of AD-amyloidosis, and to test potential treatments. So far, cerebellum tissue has not been deeply analyzed to check the amyloidosis in these transgenic models. Besides, sex influence hasn't been systematically studied in these models, even it has been described important gender differences in the evolution of AD in human population. We have checked whether the progression of amyloidosis in a double transgenic mouse, APP/PS1, is susceptible to aging and differentially affects males and females. Methods: Aß levels were measured by ELISA in plasma and tissue samples. Cortex and cerebellum tissue of transgenic males and females from 6 to 15 months of age were processed to be analyzed. In addition, fixed hemibrains brain were coronally sectioned and used to perform immunohistochemistry and immunofluorescence studies. | URI: | http://hdl.handle.net/10261/128934 |
