Abstract

Parkinson's disease (PD) is associated with the degeneration of ventral midbrain dopaminergic neurons (vmDAns) and the accumulation of toxic α-synuclein. A non-cell-autonomous contribution, in particular of astrocytes, during PD pathogenesis has been suggested by observational studies, but remains to be experimentally tested. Here, we generated induced pluripotent stem cell-derived astrocytes and neurons from familial mutant LRRK2 G2019S PD patients and healthy individuals. Upon co-culture on top of PD astrocytes, control vmDAns displayed morphological signs of neurodegeneration and abnormal, astrocyte-derived α-synuclein accumulation. Conversely, control astrocytes partially prevented the appearance of disease-related phenotypes in PD vmDAns. We additionally identified dysfunctional chaperone-mediated autophagy (CMA), impaired macroautophagy, and progressive α-synuclein accumulation in PD astrocytes. Finally, chemical enhancement of CMA protected PD astrocytes and vmDAns via the clearance of α-synuclein accumulation. Our findings unveil a crucial non-cell-autonomous contribution of astrocytes during PD pathogenesis, and open the path to exploring novel therapeutic strategies aimed at blocking the pathogenic cross talk between neurons and glial cells.

  • Non-cell autonomous mechanisms can cause dysfunction across the entire substantia nigra pars compacta, leading to rapid dopaminergic neurodegeneration, in contrast to neuron-specific cell autonomous mechanisms.

    “in contrast to neuron-specific cell autonomous mechanisms that affect individual DA neurons within the SNc, non-cell autonomous mechanisms can cause dysfunction across the entire SNc, thereby leading to rapid DA neurodegeneration”

    The Abstract and Discussion report that PD-derived astrocytes contribute to dopaminergic-neuron degeneration, including in co-culture with control neurons. The Introduction identifies the substantia nigra pars compacta as a site of dopaminergic-neuron loss, but the paper does not show dysfunction across the entire region, establish rapid degeneration, or make the stated comparison with neuron-specific mechanisms. Page numbers are unavailable in our copy. (LLM, conf=0.88)

  • Astrocytes generated from hiPSC derived from fibroblasts of patients with CNS diseases show pathological phenotypes, including dysregulation of lipid metabolism, alteration in extracellular vesicles, reduced autophagy, or altered STAT3 signaling.

    “Interestingly, astrocytes generated from hiPSC derived from fibroblasts obtained from patients with CNS diseases (usually with a genetic mutation causative of disease or a risk polymorphism) show pathological phenotypes, including dysregulation of lipid metabolism11, alteration in the contents of the extracellular vesicles released by astrocytes80, reduced autophagy81, or altered STAT3 signaling82”

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.
