🧪 Overview

Mutant HTT expression in NG2+ glial progenitors impairs their differentiation and homeostatic function, contributing to medium spiny neuron vulnerability. Transplanting wild-type progenitors or enhancing endogenous glial support may protect MSNs, though neuronal mHTT appears sufficient for disease.

🧬 Mechanism

No curated mechanism pathway recorded for this hypothesis.

⚖️ Evidence

⚖️ Evidence Matrix3 supports4 contradicts
Supports
Mutant HTT expressed in human striatal glial progenitor cells
PMID:29104264
Supports
Reduced oligodendrocyte lineage cells in HD postmortem striatum
PMID:31444072
Supports
CRISPR-mediated HTT lowering in astrocytes extends survival in BACHD mice
PMID:32554578
Contradicts
Selective deletion of mHTT from neurons rescues HD phenotypes in YAC128 mice
PMID:23160048
Contradicts
NG2+ cell density changes occur in many neurodegenerative diseases, not HD-specific
PMID:review
Contradicts
Human HD oligodendrocyte loss is mild (10-20%) compared to MSN loss (95%)
PMID:review
Contradicts
Transplanted cells may rescue via paracrine trophic support rather than cell-intrinsic correction
PMID:review
