Abstract：
:Heme oxygenase-1 is a cellular stress protein expressed in brain and other tissues in response to oxidative challenge and other noxious stimuli. In the present study, immunohistochemistry was used to assess HO-1 expression in various postmortem human brain specimens derived from PD and control subjects. In the substantia nigra of both PD and control specimens, moderate HO-1 immunoreactivity was consistently observed in neuromelanin-containing (dopaminergic) neurons. Lewy bodies in PD nigra neurons exhibited intense HO-1 immunostaining in their peripheries. In both PD and control specimens, neuronal HO-1 staining was faint or nondetectable in the other brain regions surveyed. The fraction of GFAP-positive astroglia expressing HO-1 in PD substantia nigra (77.1 +/- 12.3) was significantly greater than that observed in the substantia nigra of control subjects (18.7 +/- 7.1; P = 0.0015). In the other regions examined, percentages of GFAP-positive astroglia coexpressing HO-1 were relatively low and did not differ significantly (P > 0.05) between control and PD specimens. Upregulation of HO-1 in the substantia nigra of PD subjects supports the view that the affected tissue is experiencing chronic oxidative stress. In addition, excessive cellular levels of heme-derived free iron and carbon monoxide resulting from HO-1 overactivity may contribute to the pathogenesis of PD.
