Abstract:

A growing body of literature has established a link between the cerebral ischaemic injury and pathological state of Alzheimer's disease (AD), and this correlation indicated that the preventive agent for ischaemia might improve the pathology of AD. Our previous studies have demonstrated that Neohesperidin (NH) exhibited neuroprotective effects against cerebral ischemia via the down-regulation of Bcl-2, Akt/PI3K and Nrf2 pathways. In the present study, we first confirmed the protective effects of NH on Aβ-induced neurotoxicity on primary cultured hippocampal neurons. We further demonstrated NH attenuated Aβ-induced apoptosis by preventing neurotoxicity associated with lethal UPR and ER stress via blocking S-nitrosylation of protein-disulphide isomerase (PDI). These results suggested that S-nitrosylation of PDI and ER dysfunction might be the synergistic and synchronous pathological process between cerebral ischaemia and AD.
