The health challenges posed by Alzheimer’s disease (AD) continue to grow as societies age worldwide. Accumulation of Tau-associated pathology correlates with clinical cognitive deterioration in AD. Resident myeloid cells within the central nervous system (CNS) have a limited capacity to uptake and degrade Tau; however, the resulting secretion of proinflammatory cytokines only acts to accelerate neurodegeneration. Therapeutic antibodies can reduce the neurotoxic oligomeric form of Tau (o-Tau), but in doing so they also aggravate inflammation. Attenuating mutation of the antibody Fc region can silence inflammation but also eliminates its capacity to mediate o-Tau clearance by CNS myeloid cells. Thus, there …

The typical ‘Western Diet’ includes a diet high in fats and sugars. This thesis explores the problems that this type of diet could have on the brain. A meta-analysis was conducted to show activated microglia count in the hypothalamus of mice after a high-fat diet. The results showed a large effect size with the included studies, showing that a high fat diet significantly increases microglia count across studies. Increased activated microglia leads to chronic inflammation in the hypothalamus, which is linked to metabolic problems like insulin resistance, leptin resistance and glucose intolerance.
