Autophagosomes initiate distally and mature during transport toward the cell soma in primary neurons
Open accessAbstract
Autophagy is an essential cellular degradation pathway in neurons; defects in autophagy are sufficient to induce neurodegeneration. In this paper, we investigate autophagosome dynamics in primary dorsal root ganglion neurons. Autophagosome biogenesis occurs distally in a constitutive process at the neurite tip. Autophagosomes initially move bidirectionally and then switch to unidirectional, processive movement toward the cell soma driven by dynein. Autophagosomes copurify with anterograde and retrograde motors, suggesting that the activity of bound kinesin motors is effectively down-regulated to yield robust retrograde motility driven by dynein. Both organelle and soluble cargoes are internalized into autophagosomes, including mitochondria and ubiquitin. As autophagosomes move distally to proximally, they undergo maturation and become increasingly acidified, consistent with the formation of an autolysosomal compartment that may more efficiently degrade cargo. This maturation is accompanied by a switch to bidirectional motility characteristic of lysosomes. Together, autophagosome biogenesis and maturation in primary neurons is a constitutive process that is spatially and temporally regulated along the axon.

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.
