Background: Neuropathological studies supported by experimental animal studies show that the constituents of the innate immunity are intimately involved in the early steps of the pathological cascade of Alzheimer's disease (AD).
Objectives: To show the evidence that constituents of the innate immunity contribute to the etiology of late-onset AD.
Methods: Evaluation of the relationship between the constituents of the innate immunity and genetic risk factors for late-onset AD.
