متن کاملDiscovery of Inhibitors of Insulin-Regulated Aminopeptidase as Cognitive Enhancers
The hexapeptide angiotensin IV (Ang IV) is a metabolite of angiotensin II (Ang II) and plays a central role in the brain. It was reported more than two decades ago that intracerebroventricular injection of Ang IV improved memory and learning in the rat. Several hypotheses have been put forward to explain the positive effects of Ang IV and related analogues on cognition. It has been proposed tha...
متن کاملMechanisms of action of cognitive enhancers on neuroreceptors.
No strategies for curing Alzheimer's disease have been developed yet as we do not know the exact cause of the disease. The only therapy that is available for patients is symptomatic treatment.

Four anticholinest...
