title: Antigenic characteristics of neurofibrillary tangles in progressive supranuclear palsy.
abstract: The antigenic components of neurofibrillary tangles in the basal forebrain and brainstem were studied in 4 cases of progressive supranuclear palsy (PSP) at the light and electron microscopic levels, using antibodies to neurofilaments (in the phosphorylated and non-phosphorylated forms); the high, middle and low molecular weight neurofilament subunits; ubiquitin; the microtubule associated proteins MAP1, MAP2 and tau; isolated Alzheimer paired helical filaments and to tubulin, in the tyrosinated and detyrosinated forms. Although PSP neurofibrillary tangles appear to have most antigenic sites in common with those of Alzheimer disease, PSP tangles share epitopes with tyrosinated and detyrosinated tubulin, which has not been demonstrated in Alzheimer neurofibrillary tangles.
