title: alpha-synuclein immunopositive Parkinson's disease-related inclusion bodies in lower brain stem nuclei.
abstract: Advanced silver stains and immunohistochemical reactions against alpha-synuclein were used to detect Parkinson's disease-related cytoskeletal abnormalities in select lower brain stem nuclei. Various types of inclusion bodies including inconspicuous and heretofore unnoted granular particles and thread-like Lewy neurites were visualized. Of the nuclei investigated (gigantocellular reticular nucleus, bulbar raphe nuclei, coeruleus-subcoeruleus area), only lipofuscin- or neuromelanin-laden neuronal types showed a propensity to develop the pathological changes. Neuronal types devoid of pigment deposits remained free of the cytoskeletal abnormalities. Fine, dust-like particles and small globular Lewy bodies were encountered solely within the limits of intraneuronal lipofuscin or neuromelanin deposits.
