Abstract:
:Nitric oxide (*NO)-mediated toxicity has been involved in neurodegenerative diseases, including Parkinson's disease (PD). We have recently reported an increase of about 50% in *NO production rate in PMA-activated polymorphonuclear leukocytes (PMN) from either newly diagnosed or chronically treated PD patients. As humoral factors in sera from PD patients could inhibit cell dopaminergic activity, the aim of this study was to determine whether a plasma circulating factor from PD patients could modify *NO metabolism in PMN from healthy control subjects. To this purpose, we determined simultaneously the maximal production rate of *NO and hydrogen peroxide (H2O2) of PMA-activated PMN isolated from healthy control subjects in the presence of aliquots of plasma of PD patients. The results showed that, after 30 min incubation, plasma from newly diagnosed (n=4) or from L-Dopa chronically treated (n=7) PD patients enhanced *NO release in neutrophils isolated from healthy controls by about 50% and 47% respectively, with respect to non-parkinsonian control plasma (n = 10); in the same condition, H2O2 production did not differ among the groups. These data suggest that an overproduction of *NO related to plasma circulating factors, already detected at initial stages of the disease, participates in the pathophysiology of Parkinson's disease.
