摘      要：Alzheimer’s disease is a neurodegenerative disease that accounts for most of the 50-million dementia cases worldwide in 2018.A large amount of evidence supports the amyloid cascade hypothesis,which states that amyloid-beta accumulation triggers tau hyperphosphorylation and aggregation in form of neurofibrillary tangles,and these aggregates lead to inflammation,synaptic impairment,neuronal loss,and thus to cognitive decline and behavioral *** poor correlation found between cognitive decline and amyloid plaques,have led the scientific community to question whether amyloid-beta accumulation is actually triggering neurodegeneration in Alzheimer’s *** occurrence of tau neurofibrillary tangles better correlates to neuronal loss and clinical symptoms and,although amyloid-beta may initiate the cascade of events,tau impairment is likely the effector molecule of ***,it has been shown that amyloid-beta and tau cooperatively work to impair transcription of genes involved in synaptic function and,more importantly,that downregulation of tau partially reverses transcriptional *** mounting evidence points to an interplay between amyloid-beta and tau,some factors could independently affect both ***,the dual pathway hypothesis,which states that there are common upstream triggers causing both amyloid-beta and tau abnormalities has been *** others,the immune system seems to be strongly involved in amyloid-beta and tau *** factors,as the apolipoprotein Eε4 isoform has been suggested to act as a link between amyloid-beta and tau ***,amyloid-beta-immunotherapy reduces not only amyloid-beta but also tau levels in animal models and in clinical ***,it has been shown that tau-immunotherapy also reduces amyloid-beta ***,even though amyloid-beta immunotherapy is more advanced than tau-immunotherapy,combined amyloid-beta and tau-directed therapie
