Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by cognitive deficits, neuroinflammation, and loss of neurons. Recently, it has been shown that ghrelin, a 28 amino acid peptide hormone produced from the stomach and hypothalamus, has been reported as a potential therapeutic agent for several neurological disorders, including Parkinson's disease (PD), stroke, epilepsy, multiple sclerosis, and spinal cord injury. ⋯ Taken together, our findings demonstrate that ghrelin can ameliorate AβO-induced cognitive impairment associated with neuroinflammation and neuronal loss. These results suggest that ghrelin may be a promising therapeutic agent for the treatment of AD.
