The Interface between Cytoskeletal Aberrations and Mitochondrial Dysfunction in Alzheimer s Disease and Related Disorders Kang DE; Roh SE; Woo JA; Liu T; Bu JH; Jung AR; Lim YExp Neurobiol 2011[Jun]; 20 (2): 67-80The major defining pathological hallmarks of Alzheimer's disease (AD) are the accumulations of Abeta in senile plaques and hyperphosphorylated tau in neurofibrillary tangles and neuropil threads. Recent studies indicate that rather than these insoluble lesions, the soluble Abeta oligomers and hyperphosphorylated tau are the toxic agents of AD pathology. Such pathological protein species are accompanied by cytoskeletal changes, mitochondrial dysfunction, Ca(2+) dysregulation, and oxidative stress. In this review, we discuss how the binding of Abeta to various integrins, defects in downstream focal adhesion signaling, and activation of cofilin can impact mitochondrial dysfunction, cytoskeletal changes, and tau pathology induced by Abeta oligomers. Such pathological consequences can also feedback to further activate cofilin to promote cofilin pathology. We also suggest that the mechanism of Abeta generation by the endocytosis of APP is mechanistically linked with perturbations in integrin-based focal adhesion signaling, as APP, LRP, and beta-integrins are physically associated with each other.ä |
