: Alzheimer’s disease (AD) is a chronic neurodegenerative disease characterized by the formation of intracellular neurofibrillary tangles (NFTs) and extracellular amyloid plaques. Growing evidence has suggested that AD pathogenesis is not only limited to the neuronal compartment but also strongly interacts with immunological processes in the brain. On the other hand, aggregated and misfolded proteins can bind with pattern recognition receptors located on astroglia and microglia and can in turn induce an innate immune response, characterized by the release of inflammatory mediators, ultimately playing a role in both the severity and the progression of the disease. It has been reported by genome-wide analysis that several genes which elevate the risk for sporadic AD encode for factors controlling the inflammatory response and glial clearance of misfolded proteins. Obesity and systemic inflammation are examples of external factors which may interfere with the immunological mechanisms of the brain and can induce disease progression. In this review, we discussed the mechanisms and essential role of inflammatory signaling pathways in AD pathogenesis. Indeed, interfering with immune processes and modulation of risk factors may lead to future therapeutic or preventive AD approaches.

ABSTRACTBackground:The apolipoprotein E (APOE) genotype provides information about Alzheimer’s disease risk, yet genotype disclosure is discouraged due to concerns about possible distress. This is the first study investigating the psychological and behavioral impacts that genetic susceptibility testing for Alzheimer’s disease has in an Asian population.Methods:From March 2016 to November 2017, we ran a prospective cohort study at Duke-National University of Singapore Medical School. 280 healthy Chinese elderly filled in questionnaires that measured psychological symptoms and health behaviors, 1 week before and 6 weeks afterAPOEgenotype disclosure. Responses from ε4-positive subjects (associated with greater Alzheimer’s disease risk) were compared to responses from ε4-negative subjects.Results:ε4 presence was not significantly associated with anxiety (p= 0.09) or depression (p= 0.25). No associations were found for changes to diet (p= 0.36), dietary supplements consumption (p= 0.90), physical activity (p= 0.15), or cognitive activity (p= 0.18).Conclusion:There is no evidence to suggest that disclosure ofAPOEto Asian populations was associated with any short-term adverse psychological or behavioral impacts.
