Abstract

Neurotrophic factors are promising candidates for the treatment of Parkinson's disease (PD). Mesencephalic astrocyte-derived neurotrophic factor (MANF) belongs to a novel evolutionarily conserved family of neurotrophic factors. We examined whether MANF has neuroprotective and neurorestorative effect in an experimental model of PD in rats. We also studied the distribution and transportation of intrastriatally injected MANF in the brain and compared it with glial cell line-derived neurotrophic factor (GDNF). Unilateral lesion of nigrostriatal dopaminergic system was induced by intrastriatal injection of 6-hydroxydopamine (6-OHDA). Amphetamine-induced turning behavior was monitored up to 12 weeks after the unilateral lesion. The local diffusion at the injection site and transportation profiles of intrastriatally injected MANF and GDNF were studied by immunohistochemical detection of the unlabeled growth factors as well as by autoradiographic and gamma counting detection of 125 I-labeled trophic factors. Intrastriatally injected MANF protected nigrostriatal dopaminergic nerves from 6-OHDA-induced degeneration as evaluated by counting tyrosine hydroxylase (TH)-positive cell bodies in the substantia nigra (SN) and TH-positive fibers in the striatum. More importantly, MANF also restored the function of the nigrostriatal dopaminergic system when administered either 6 h before or 4 weeks after 6-OHDA administration in the striatum. MANF was distributed throughout the striatum more readily than GDNF. The mechanism of MANF action differs from that of GDNF because intrastriatally injected 125 I-MANF was transported to the frontal cortex, whereas 125 I-GDNF was transported to the SN. Our results suggest that MANF is readily distributed throughout the striatum and has significant therapeutic potential for the treatment of PD.

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.
