Abstract

Transactive response DNA-binding (TDP-43) protein is the dominant disease protein in amyotrophic lateral sclerosis (ALS) and a subgroup of frontotemporal lobar degeneration (FTLD-TDP). Identification of mutations in the gene encoding TDP-43 ( TARDBP ) in familial ALS confirms a mechanistic link between misaccumulation of TDP-43 and neurodegeneration and provides an opportunity to study TDP-43 proteinopathies in human neurons generated from patient fibroblasts by using induced pluripotent stem cells (iPSCs). Here, we report the generation of iPSCs that carry the TDP-43 M337V mutation and their differentiation into neurons and functional motor neurons. Mutant neurons had elevated levels of soluble and detergent-resistant TDP-43 protein, decreased survival in longitudinal studies, and increased vulnerability to antagonism of the PI3K pathway. We conclude that expression of physiological levels of TDP-43 in human neurons is sufficient to reveal a mutation-specific cell-autonomous phenotype and strongly supports this approach for the study of disease mechanisms and for drug screening.

  • Familial ALS patient iPSC-derived motor neurons with TDP-43 mutation showed decreased voltage-activated Na+ and K+ currents and increased vulnerability.

    “Familial ALS patient iPSC-derived motor neurons with TDP-43 mutation showed decreased voltage-activated Na+ and K+ currents and increased vulnerability [39].”

    From Utility of iPSC-Derived Cells for Disease Modeling, Drug Development, and Cell Therapy (2022) · cites this paper as [39]

    The Results (p. 3) report greater vulnerability of TDP-43 M337V motor-neuron cultures to PI3K inhibition, and the Discussion (p. 3) reports reduced neuronal survival under basal conditions. But the paper does not report decreased voltage-activated Na+ or K+ currents; its Results (p. 2) instead describe mutant and control motor neurons as functionally comparable. (LLM, conf=0.88)

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.
