WebThe cellular and molecular mechanisms that govern presynaptic dystrophic neurite formation are unclear, and elucidating these processes may lead to novel AD … Webdystrophic neurites (tau-containing degenerated axons and dendrites surrounding Aβ plaques). Although these structures can be seen in some brainstem nuclei in young adults 69 , tauopathy in the medial temporal lobe is the initial site relevant to cognition 70 , 71. Medial temporal tauopathy may occur independently of Aβ pathology 72 , 73.
WebDystrophic neurites are abnormal neuronal processes characterized microscopically by aberrant sprouting, dystrophic expansion, and accumulation of various cellular organelles and cytoskeletal/signaling proteins. Neurite dystrophy. MedGen UID: 990675 WebFeb 29, 2000 · The appearance of these dystrophic neurites was very similar to those seen surrounding thioflavine-S-positive deposits in AD brain by using the same method (Fig. 1). These findings support the possibility that the process of structural changes in which Aβ is converted from a “soluble/diffuse” form to a “fibrillar” form results in the ...
