 AB    The etiology of Parkinson's disease is mainly unknown. Immune
       abnormalities have been described, but the cause of such abnormalities
       has not been resolved. We examined by two-colour flow cytometry HLA-DR
       antigen expression on monocytes from cerebrospinal fluid (CSF) and blood
       and, moreover, lymphocyte subpopulations (CD4+ CD45RO+, CD4+ CD45RA+,
       CD8+ CD11b+high) in peripheral blood from patients with Parkinson's
       disease compared with age-matched patients with other neurological
       diseases (OND) and tension headache. We found higher HLA-DR expression
       on CSF monocytes compared with blood monocytes. This difference was
       restricted to Parkinson's disease patients. T helper cell analysis
       revealed a decreased percentage of CD45RA+ naive and an increased
       percentage of CD45RO+ memory T cell subset from CD4+ T cells in
       peripheral blood of patients with Parkinson's disease compared with
       patients with tension headache. The proportions of CD8+ CD11b+high
       suppressor T cells remained unchanged, among the three patient groups
       compared. A selective loss of CD4+ CD45RA+ cells, previously observed in
       diseases like multiple sclerosis and Down's syndrome as compared with
       healthy controls suggests a common immunological abnormality in
       neurological disorders.
