Chaperone-Mediated Autophagy Markers in Parkinson Disease Brains
Abstract
OBJECTIVE: To investigate chaperone-mediated autophagy in the pathogenesis of Parkinson disease (PD). DESIGN: Postmortem observational study. SETTING: University Department of Clinical Neuroscience, Institute of Neurology, University College London. SUBJECTS: Postmortem samples from 7 PD, 6 Alzheimer disease (AD), and 8 control brains. MAIN OUTCOME MEASURE: Lysosomal-associated membrane protein 2A (LAMP2A) and heat shock cognate 70 (hsc70) protein levels were compared in the substantia nigra pars compacta and amygdala of PD, AD, and control brain samples. To provide insight into the turnover of α-synuclein, degradation pathways for this protein were studied in a dopaminergic cell line. RESULTS: The expression levels of the chaperone-mediated autophagy proteins LAMP2A and hsc70 were significantly reduced in the substantia nigra pars compacta and amygdala of PD brains compared with age-matched AD and control brain samples. Lewy bodies in these regions contained autophagy-related proteins. We demonstrated that decreased LAMP2A levels in dopaminergic cell lines reduced chaperone-mediated autophagy activity and increased the half-life of α-synuclein. CONCLUSIONS: These findings suggest that there is reduced chaperone-mediated autophagy activity in the PD brain, provide evidence for the role of autophagy in PD pathogenesis and Lewy body formation, and suggest that this pathway may be a suitable therapeutic target in 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.
