Alzheimer's disease: new concepts on the role of autoimmunity and of NLRP3 inflammasome in the pathogenesis of the disease
Alzheimer's disease (AD), recognized as the most common neurodegenerative disorder, is clinically characterized by the presence of extracellular beta amyloid (Aβ) plaques and by intracellular neurofibrillary tau tangles, accompanied by glial activation and neuroinflammation. Increasing evidence suggests that self-misfolded proteins stimulate an immune response mediated by glial cells, inducing release of inflammatory mediators and the recruitment of peripheral macrophages into the brain, which in turn aggravate AD pathology.
