摘      要：Due to the aging of the population and despite the enormous scientific effort,Alzheimer s disease remains one of the biggest medical and pharmaceutical challenges in current *** insights highlight the importance of neuroinflammation as an undeniable player in the onset and progression of Alzheimer s *** necrosis factor is a master inflammatory cytokine that signals via tumor necrosis factor receptor 1 and tumor necrosis factor receptor 2,but that also regulates several brain functions in health and ***,clinical trials investigating drugs that interfere with the tumor necrosis factor pathway in Alzheimer s disease led to inconclusive results,partially because not only the pro-inflammatory tumor necrosis factor/tumor necrosis factor receptor 1,but also the beneficial tumor necrosis factor/tumor necrosis factor receptor 2 signaling was antagonized in these *** recently found that tumor necrosis factor is the main upregulated cytokine in the choroid plexus of Alzheimer s disease patients,signaling via tumor necrosis factor receptor *** agreement with this,choroidal tumor necrosis factor/tumor necrosis factor receptor 1 signaling was also upregulated in different Alzheimer s disease mouse ***,both genetic and nanobody-based pharmacological blockage of tumor necrosis factor receptor 1 signaling was accompanied by favorable effects on Alzheimer s disease-associated inflammation,choroidal morphology and cognitive ***,we briefly summarize the detrimental effects that can be mediated by tumor necrosis factor/tumor necrosis factor receptor 1 signaling in(early) Alzheimer s disease,and the consequences this might have on the disease *** the main hypothesis in Alzheimer s disease clinical trials is still based on the amyloid beta-cascade,the importance of Alzheimer s disease-associated neuroinflammation urge the development of novel therapeutic strategies that might be effective in the early stages
