Genetic predisposition to inflammation: a new risk factor of Alzheimer's disease / 神经科学通报·英文版

ABSTRACT

Inflammation has been shown to play an important role in the progression of Alzheimer's disease (AD). Recent epidemical study indicates that the incidence of AD in some populations is substantially influenced by the gene polymorphisms of the inflammation mediators. Meanwhile, an ensured risk factor, the ApoE epsilon4 allele is also reported to directly promote inflammation. Accordingly, it appears that an individual genetic background has partly determined his predisposition for AD by the extent of the inflammation response to the chronic stimulus by beta-amyloid peptide (Abeta) deposits and other antigen stressor in the elderly. Hence we present a hypothesis that the inflammation genotypes may contribute to AD susceptibility. This may provide a new orientation both for future identification of individuals at risk and for personalized medication.
