Abstract

Eosinophilic cytoplasmic inclusions in dopaminergic nigrostriatal neurons, the primary component of which is α-synuclein, are the pathological hallmark of Parkinson's disease (PD) [ [1] Hughes A.J. Daniel S.E. Lees A.J. Improved accuracy of clinical diagnosis of Lewy body Parkinson's disease. Neurology. 2001; 57: 1497-1499 Crossref PubMed Scopus (627) Google Scholar ]. Nerve fibers immunoreactive to phosphorylated α-synuclein have been identified in postmortem [ [2] Beach T.J. Adler C.H. Dugger B.N. Serrano G. Hidalgo J. Henry-Watson J. Shill H.A. Sue L.I.

Here we measured phosphorylated-α-synuclein immunoreactivity in nerve fibers from minor salivary gland biopsy in PD. The study was approved by the “Sapienza” University Ethical Committee .
