MeSH definition : Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY
TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER
DISEASE. Neuropil threads are made up of straight and paired helical filaments which
consist of abnormally phosphorylated microtubule-associated tau proteins. It has been
suggested that the threads have a major role in the cognitive impairment seen in Alzheimer
disease.;
MeSH synonym : neuropil thread;
MeSH annotation : do not confuse with NEUROPIL, a felt of interwoven neuronal components & neuroglia;
