dc.description.abstractAlzheimer's disease (AD) is the most common neurodegenerative disorder. AD is defined by progressive memory loss and cognitive impairments and at the molecular level by the presence of neurofibrillary tangles, composed of hyperphosphorylated Tau fibrils, and Aâ-containing amyloid plaques. Antihypertensive treatments have been associated with lower incidence of clinically diagnosed AD and better cognitive function, and it has been tested whether some antihypertensive drugs might influence AD through mechanisms independent of blood pressure-lowering activity. Propranolol, a â-adrenergic antagonist that is commonly used in the treatment of hypertension, shown experimentally to reverse cognitive deficits associated to stress and decrease of Aâ levels in vitro. In this work, we study the effect of propranolol in three animal models representing the three main groups of risk factors associated with the development of AD (age, genetics and environmental factors). After chronic treatment with propranolol at a lower dose than that used as antihypertensive (5 mg/kg), we evaluated the cognitive status of animals and different markers of AD in the hippocampus. In all cases, propranolol was able to reverse the increased levels of Aâ and hyperphosphorylated Tau. These effects may contribute to cognitive enhancement found in the three experimental models. In conclusion, propranolol seems to exert a protective role against disease neuropathology, making it a potential candidate for the treatment of AD.es_ES
