Summary
Cuprizone and lysophosphatidylcholine mouse models show distinct oligodendrocyte responses to demyelination, with some shared immune pathways during repair, but neither fully captures human multiple sclerosis complexity.
Area of Science:
- Neuroscience
- Immunology
- Genomics
Background:
- Demyelinating diseases like multiple sclerosis (MS) involve myelin loss and neurodegeneration.
- The comparability of cuprizone (CPZ) and lysophosphatidylcholine (LPC) mouse models to human MS remains unclear.
Purpose of the Study:
- To integrate single-cell transcriptomic data from CPZ and LPC models with human MS data.
- To compare glial cell responses across species and models of demyelination.
Main Methods:
- Single-cell RNA sequencing (scRNA-seq) data integration.
- Comparative transcriptomic analysis of CPZ-induced, LPC-induced, and human MS datasets.
Main Results:
- CPZ models induce a unique stressed oligodendrocyte state (Cdkn1a, Nupr1) resembling MS lesions.
- Both models show an immune-responsive oligodendrocyte state (Socs3, B2m, interferon genes) during remyelination.
- Mouse microglia share activation programs, but LPC elicits a stronger, sustained response; neither model fully replicates MS glial heterogeneity.
Conclusions:
- Mouse models exhibit distinct and shared glial responses relevant to demyelination.
- Neither CPZ nor LPC models fully recapitulate the cellular heterogeneity seen in human MS.
- Findings provide a cross-species atlas to guide the use of mouse models for studying myelin repair.
