摘要
Alzheimer's disease (AD) is characterized by the formation of insoluble deposits of beta-amyloid (A beta) within the parenchyma of the brain. These deposits are associated with a robust microglia-mediated inflammatory response. Recent work has demonstrated that Toll-like receptors (TLRs) participate in this inflammatory response. This chapter reviews the mechanisms whereby TLRs contribute to the induction of a microglial inflammatory response to promote AD pathogenesis. Specifically, the involvement of CD14 and the TLRs in microglial activation is delineated. The TLR-mediated microglial response has beneficial roles in stimulating phagocytosis as well as detrimental roles in the AP-stimulated release of neurotoxic products.
