Reaction of Lewy bodies with antibodies to phosphorylated and non-phosphorylated neurofilaments.
The reaction of Lewy bodies in the substantia nigra and the sympathetic ganglia was studied in 10 cases of Parkinson's disease and other Lewy body-related conditions, using monoclonal antibodies to non-phosphorylated (02-40) and phosphorylated (03-44 and 07-5) neurofilaments. Although many Lewy bodies were unstained, a peripheral ring of positive immunoreactivity was frequently observed. This reaction was more common and more intense with antibodies to phosphorylated neurofilaments, suggesting a posttranslational phosphorylation of elements in the Lewy body. Although Lewy bodies appear to have some antigenic sites in common with neurofilaments, certain differences between neurofilaments and Lewy body filaments are emphasized.
