Inter- estingly generic 50mg clomiphene with visa, they have also shown that reductions are observed The concept that a genetically regulated cell death process in patients with incidental Lewy body disease order clomiphene 50mg with visa, which may may underlie the neuron-specific degenerations of later life be a preclinical form of PD (49). This finding suggests that has gathered great attention in recent years. The pro- the reduced levels of glutathione may be a fundamental and grammed cell death hypothesis in fact may be related to primary abnormality in PD, rather than a secondary change. Although A number of postmortem studies have also suggested traditional concepts of free radical injury have centered on that abnormalities of iron metabolism may underlie the neu- the ability of toxic molecules to directly injure cellular con- rodegeneration of PD. It is also apparent that in some settings Dexter and colleagues (26) reported increased levels of iron programmed cell death may be carried out by the controlled in the SNpc of PD patients. This observation took on po- production of free radicals.

Nevertheless, the possible relationship of altered labeling technique to identify apoptotic natural cell death iron metabolism to the pathogenesis of PD remains of inter- in phenotypically defined dopaminergic neurons (123). There is an initial, major peak that begins on embry- (35). This finding suggests that lactoferrin receptors, which onic day 20, and largely abates by the eighth postnatal day regulate intraneuron iron content, may be overly expressed (PND). There is a second, minor peak of natural cell death in vulnerable dopaminergic neurons in PD. The presence of a postnatal cell death event Another postmortem finding in PD patients that is com- is in keeping with the demonstration by Tepper and col- patible with the free radical hypothesis is that of a deficiency leagues (151) that there is a decrement in the number of in mitochondrial complex I. Such a defect could either result TH-positive neurons in SN postnatally, particularly in the in the abnormal production of free radicals, or be the result first postnatal week. Although there is evidence that the of free radical injury (137). This defect takes on particular magnitude of the natural cell death event in DA neurons interest in light of the observation that MPP , the toxic is regulated by interactions with the target striatum (see oxidative product of MPTP, inhibits complex I (121).

Whether glial cell TUNEL labeling (45) has been demonstrated in PD brains line-derived neurotrophic factor (GDNF) plays such a role (115). However, the terminal deoxynucleotidyl transferase in vivo remains to be determined. Excitotoxic injury to the striatum on PND 7 results in an Thus, it is essential to co-identify not only TUNEL labeling eightfold increase in the number of apoptotic profiles (102). Tompkins and co-workers (153) and Tatton and served during natural cell death, and meet ultrastructural colleagues (150) have both achieved this more specific dem- and 3′ end-labeling criteria for apoptosis. However, many other investigators have been induction of cell death is identified within phenotypically unable to identify specific TUNEL labeling in PD brains defined dopaminergic neurons. Thus, a consensus has not been achieved, Programmed cell death also occurs in DA neurons in and further investigation will require methods beyond these animal models of parkinsonism. Intrastriatal injection of 6- morphologic techniques, such as the utilization of specific OHDA results in an induction of apoptotic death in pheno- biochemical markers for programmed cell death.

Interestingly, at older ages fied in Lewy body–containing neurons of the SN in PD the morphology of cell death becomes mixed, including brains (58).
