Intrastriatal implantation of fibroblasts genetically engineered to produce brain-derived neurotrophic factor prevents degeneration of dopaminergic neurons in a rat model of Parkinson’s disease
Open accessAbstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by a progressive loss of the dopaminergic neurons of the substantia nigra pars compacta (SNpc). Although various treatments are successfully used to alleviate the symptoms of PD, none of them prevents or halts the neurodegenerative process of the disease. Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family of proteins, supports the survival and the differentiation of dopaminergic neurons. BDNF also prevents the death of dopaminergic neurons in vitro, which suggests that it may be of possible use in the development of neuroprotective therapies for PD. To determine whether BDNF is neuroprotective for SNpc dopaminergic neurons in the adult brain, we used a rat model of PD in which degeneration of 60-70% of these neurons was induced by an intrastriatal injection of 6-hydroxydopamine (6-OHDA). We report here that intrastriatal grafts of fibroblasts genetically engineered to produce BDNF partially prevent the loss of nerve terminals and completely prevent the loss of cell bodies of the nigrostriatal dopaminergic pathway that is induced by the intrastriatal injection of 6-OHDA. In contrast, the implantation of control fibroblasts that did not produce BDNF failed to protect nerve terminals and cell bodies against 6-OHDA-induced damage. Our observation that grafts of BDNF-producing fibroblasts protect against 6-OHDA-induced degeneration of SNpc dopaminergic neurons in the adult rat brain opens new perspectives for treatments aimed at the prevention of neurodegeneration in PD, using gene therapy and neurotrophic factors such as BDNF.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
