Neurofibrils
Neurofibrils are fine fibrous structures in nerve cells that consist mainly of neurofilaments (a form of intermediate filaments) and other components of the cytoskeleton. They run in bundles through the cell body and the extensions of neurons and contribute significantly to the stabilization and shaping of the nerve cell. They appear as characteristic features of neurons even in the early embryo. Alzheimer's disease causes profound changes in cytoskeletal structures: the protein tau, which normally stabilizes microtubules, becomes excessively phosphorylated, detaches from the microtubules, and aggregates to form the typical neurofibrillary tangles (fibrillary bundles). These are a central pathological feature of the disease.
