I studied immunocytochemically the neuropil threads and neurofibrillary tangles in aged and Alzheimer's disease brains using a confocal laser scanning fluorescence microscope. Some of the neuropil threads visualized by tau antibodies were shown to occur in small dendrites, although the majority of the threads were not continuous with dendritic branches. This may suggest that normal neuronal cytoskeletons are liable to disappear in thread-bearing neurites. Double-labelling with tau/ ubiquitin antibodies revealed that ubiquitin-immunoreactivities were lacking at one, or more often, both ends of the tau-positive threads.
