| Research Abstract |
Lewy bodies (LBs) containing alpha-synuclein are the hallmark lesions of Lewy body disease, including Parkinson disease (PD), PD with dementia, dementia with LBs and pure autonomic failure. Since protease treatment is known to enhance the immunoreactivity of abnormal alpha-synuclein, we immunohistochemically examined the abdominal skin tissue in LBD using anti-alpha-synuclein antibody with protease treatment. Protease-resistant alpha-synuclein is depositd in nerve fascicles mainly around blood vessels in LBD, but not in control subjects. The sensitivity of the positive skin immunoreactivity was 57.7% in subclinical PD, 88.2% in PD and PD with dementia and 53.8% in dementia with LBs. The sensitivity is higher than that using anti-phosphorylated alpha-synuclein antibody. Skin biopsy with ant-alpha-synuclein antibody may have diagnostic application in cases of LBD.
