| pubmed-article:2975511 | pubmed:abstractText | [3H]Spiperone binding to lymphocytes in Parkinson's disease (PD), Wilson's disease (WD), and age-matched control groups was studied. In the untreated PD group, [3H]spiperone binding was lower than in young controls, but did not differ from elderly healthy persons. After treatment with levodopa, the number of [3H]spiperone binding sites increased. In WD, lower binding of [3H]spiperone compared with age-matched controls was found. However, the magnitude of the differences in [3H]spiperone binding to lymphocytes in PD was too small to permit its use as a routine indicator of the disease state or the adequacy of pharmacological treatment in individual patients. [3H]Spiperone binding to lymphocytes decreases with age. Changes in [3H]spiperone binding to lymphocytes may be a general phenomenon for all states where dopamine is depleted, including normal aging. The nature of [3H]spiperone binding to lymphocytes remains unclear. The possible influence of dopamine on immune reactivity is discussed. | lld:pubmed |
