Immunofluorescence staining was performed on frontal cortex and occipital cortex tissue from cases of primary tauopathies and controls without neurodegenerative disease using antibodies to identify nucleoporin 98, phospho-tau (Ser202, Thr205) monoclonal antibody and neuronal marker microtubule-associated protein 2. Here, MAP2 is linked to neurodegenerative disease.
