title: A filamentous inclusion body within anterior horn neurones in motor neurone disease defined by immunocytochemical localisation of ubiquitin.
abstract: Using an immunocytochemical method to localise antibodies to ubiquitin, filamentous inclusion bodies were seen in spinal anterior horn neurones in cases of motor neurone disease (MND) but not in any control cases. These inclusion bodies appeared to be closely associated with classical Bunina bodies and immuno-electron microscopy suggested that they were based on arrays of straight 10-15 nm filaments together with some granular material. These observations link the protein ubiquitin with a chronic neurodegenerative disease and extend previous observations of a close association between filamentous inclusion bodies and ubiquitin. Ubiquitin-filament inclusions should be regarded as a new hallmark in the histological diagnosis of MND.
