Abstract

Huntington's disease (HD) is characterized by hypomyelination and neuronal loss. To assess the basis for myelin loss in HD, we generated bipotential glial progenitor cells (GPCs) from human embryonic stem cells (hESCs) derived from mutant Huntingtin (mHTT) embryos or normal controls and performed RNA sequencing (RNA-seq) to assess mHTT-dependent changes in gene expression. In human GPCs (hGPCs) derived from 3 mHTT hESC lines, transcription factors associated with glial differentiation and myelin synthesis were sharply downregulated relative to normal hESC GPCs; NKX2.2, OLIG2, SOX10, MYRF, and their downstream targets were all suppressed. Accordingly, when mHTT hGPCs were transplanted into hypomyelinated shiverer mice, the resultant glial chimeras were hypomyelinated; this defect could be rescued by forced expression of SOX10 and MYRF by mHTT hGPCs. The mHTT hGPCs also manifested impaired astrocytic differentiation and developed abnormal fiber architecture. White matter involution in HD is thus a product of the cell-autonomous, mHTT-dependent suppression of glial differentiation.

  • hiPSC glial mouse chimeric brains offer the possibility to study human astrocytes from patients in contexts amenable to in vivo experimentation.

    “hiPSC glial mouse chimeric brains, in which hiPSC differentiate into human astrocytes, oligodendrocytes, and their progenitors, offer the possibility to study human astrocytes from patients in contexts amenable to in vivo experimentation113,114”

    From Reactive astrocyte nomenclature, definitions, and future directions (2021) · cites this paper as [114]

    The Results section ('mHTT impairs human astroglial differentiation in vivo'; page not provided) describes studying human astrocytes in glial-engrafted mouse brains, supporting the in vivo model. But the Experimental Model section (page not provided) says the Huntington’s disease glial progenitors came from human embryonic stem cells, not patient-derived hiPSCs; the iPSC line mentioned in the Results was a control. (LLM, conf=0.88)

  • Intrastriatal engraftment of mHTT-expressing human glial progenitor cells in immunodeficient mice results in neuronal hyperexcitability in the striatum along with motor impairments.

    “Furthermore, intrastriatal engraftment of mHTT-expressing human glial progenitor cells in immunodeficient mice results in neuronal hyperexcitability in the striatum along with motor impairments (Benraiss et al. , 2016; Osipovitch et al. , 2019).”

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.
