The role of protein ubiquitination in neurodegenerative disease.

Ubiquitin immunocytochemistry with an antiserum which reacts with ubiquitin-protein conjugates demonstrates the presence of ubiquitinated proteins in filamentous inclusions found in neurones in the major human neurodegenerative diseases, i.e. Alzheimer's disease, diffuse Lewy body disease, motor neurone disease. Ubiquitin immunohistochemistry has revolutionized the neuropathological diagnosis of dementia showing that diffuse Lewy body disease is not, as previously supposed, a rare cause of dementia. The filamentous inclusions in neurones in the human neurodegenerative diseases can be divided into at least two types based on recent immunocytochemical studies. We have shown that a ubiquitin-carboxyl terminal hydrolase is present in Lewy bodies but not in neurofibrillary tangles in Alzheimer's disease. This observation is significant since it indicates that molecular pathological mechanisms in neurones in diffuse Lewy body disease are fundamentally different to Alzheimer's disease. Ubiquitin-protein conjugates are also found in vacuoles in areas of granulovacuolar degeneration in hippocampal neurones in Alzheimer's disease and in granulovacuoles in neurones of scrapie infected mouse brain. These locations suggest that ubiquitinated protein are present in the lysosome-related system of neurones. We have recently shown that ubiquitin-protein conjugates are indeed enriched some 12-fold in the lysosomes of normal fibroblasts and lymphocytes.[1]
