Abstract

Transactive response DNA-binding protein 43 kD (TDP-43) is an aggregation-prone prion-like domain-containing protein and component of pathological intracellular aggregates found in most amyotrophic lateral sclerosis (ALS) patients. TDP-43 oligomers have been postulated to be released and subsequently nucleate TDP-43 oligomerization in recipient cells, which might be the molecular correlate of the systematic symptom spreading observed during ALS progression. We developed a novel protein complementation assay allowing quantification of TDP-43 oligomers in living cells. We demonstrate the exchange of TDP-43 between cell somata and the presence of TDP-43 oligomers in microvesicles/exosomes and show that microvesicular TDP-43 is preferentially taken up by recipient cells where it exerts higher toxicity than free TDP-43. Moreover, studies using microfluidic neuronal cultures suggest both anterograde and retrograde trans-synaptic spreading of TDP-43. Finally, we demonstrate TDP-43 oligomer seeding by TDP-43–containing material derived from both cultured cells and ALS patient brain lysate. Thus, using an innovative detection technique, we provide evidence for preferentially microvesicular uptake as well as both soma-to-soma “horizontal” and bidirectional “vertical” synaptic intercellular transmission and prion-like seeding of TDP-43.

  • Pathological TDP-43 can be transferred between cells in culture, leading to seeding and pathological mislocalization in recipient cells.

    “Elegant experiments have demonstrated that pathological TDP-43 can be transferred between cells in culture (Feiler et al. 2015, Shimonaka et al. 2016), leading to seeding and pathological mislocalization in recipient cells.”

    From The Role of Retrotransposons and Endogenous Retroviruses in Age-Dependent Neurodegenerative Disorders (2024) · cites this paper as Feiler et al. 2015

    The Results section on TDP-43 oligomerization in recipient cells reports that cell-culture-derived TDP-43 was taken up and triggered oligomerization; the Discussion also reports seeding activity and granule formation in target cells. Feiler et al. do not demonstrate pathological mislocalization of the recipient cells’ TDP-43. The Introduction attributes nuclear-to-cytoplasmic redistribution to Zhu et al. (2014). (LLM, conf=0.85)

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.
