Amyloid β peptide (Aβ) has been thought to be neurotoxic and responsible for the impairment of learning and memory in Alzheimer's disease (AD). Humanin (HN), a 24 amino acid polypeptide first identified from the unaffected occipital lobe of an AD patient, is believed to be neuroprotective against the AD‐related neurotoxicity. In this study, we investigated the neuroprotective effects of Colivelin...
Rattin, a specific derivative of humanin in rats, shares the ability with HN to protect neurons against amyloid β (Aβ) peptide‐induced cellular toxicity. However, it is still unclear whether Rattin can protect against Aβ‐induced deficits in cognition and synaptic plasticity in rats. In the present study, we observed the effects of Rattin and Aβ31–35 on the spatial reference memory and in vivo hippocampal...
Alzheimer's disease (AD), the most prevalent neurodegenerative disease in the elderly, leads to progressive loss of memory and cognitive deficits. Amyloid‐β protein (Aβ) in the brain is thought to be the main cause of memory loss in AD. Melatonin, an indole hormone secreted by the pineal gland, has been reported to produce neuroprotective effects. We examined whether melatonin could protect Aβ‐induced...
