Putaminal Upregulation of FosB/Delta FosB-Like Immunoreactivity in Parkinson's Disease Patients with Dyskinesia
(2011) In Journal of Parkinson's Disease 1(4). p.347-357- Abstract
- The transcription factor Delta FosB is a mediator of maladaptive neuroplasticity in animal models of Parkinson's disease (PD) and L-DOPA-induced dyskinesia. Using an antibody that recognizes all known isoforms of FosB and Delta FosB, we have examined the expression of these proteins in post-mortem basal ganglia sections from PD patients. The patient cases were classified as being dyskinetic or non-dyskinetic based on their clinical records. Sections from neurologically healthy controls were also included in the study. Compared to both controls and non-dyskinetic cases, the dyskinetic group showed a higher density of FosB/Delta FosB-immunopositive cells in the posterior putamen, which represents the motor region of the striatum in primates....

Compared to both controls and non-dyskinetic cases, the dyskinetic group showed a higher density of FosB/Delta FosB-immunopositive cells in the posterior putamen, which represents the motor region of the striatum in primates. In contrast, the number of FosB/Delta FosB-positive cells did not differ significantly among the groups in the caudate, a region primarily involved with the processing of cognitive and limbic-related information. Only sparse FosB/Delta FosB immunoreactivity was found in the in the pallidum externum and internum, and no significant group differences were detected in these nuclei. The putaminal elevation of FosB/Delta FosB-like immunoreactivity in patients who had been affected by L-DOPA-induced dyskinesia is consistent with results from both rat and non-human primate models of this movement disorder. The present findings support the hypothesis of an involvement of Delta FosB-related transcription factors in the molecular mechanisms of L-DOPA-induced dyskinesia. (Less)
