METH use is associated with cognitive impairments and neurochemical abnormalities comparable to pathological changes observed in Alzheimer's disease (AD). These observations have stimulated the idea that METH abusers might be prone to develop AD-like signs and symptoms. Melatonin, the pineal hormone, is considered as a potential therapeutic intervention against AD. We thus conducted the present study to explore potential protective roles of melatonin against METH-induced deficits in learning and memory as well as in the appearance of AD-like pathological changes in METH-treated male Wistar rats. We found that melatonin ameliorated METH-induced cognitive impairments in those rats. Melatonin prevented METH-induced decrease in dopamine transporter (DAT) expression in rat hippocampus. Melatonin reversed METH-induced activation of β-arrestin2, reduction of phosphorylation of protein kinase B (Akt) and METH-induced excessive activity of glycogen synthase kierapeutic agent to prevent METH-induced AD like pathology.Endoplasmic reticulum stress (ERS) is known to be an essential target in protecting against ischaemic brain injury. In this study, using a vascular dementia (VaD) animal model induced by bilateral common carotid artery occlusion (BCCAO), we evaluated the effect and mechanism of 17β-oestradiol (E2) against VaD by inhibiting ERS at the early stage (14 d, 21 d, 28 d) and late stage (3 m) after BCCAO in the hippocampal CA1 region of ovariectomized rats. The results showed that the activation of the PERK-eIF2α-ATF4-CHOP axis, a typical ERS pathway, was significantly increased at the early and late stages after BCCAO. JNK (c-Jun N-terminal kinase)
