Abstract

Cuprizone administration in mice provides a reproducible model of demyelination and spontaneous remyelination, and has been useful in understanding important aspects of human disease, including multiple sclerosis. In this study, we apply high spatial resolution quantitative MRI techniques to establish the spatio-temporal patterns of acute demyelination in C57BL/6 mice after 6 weeks of cuprizone administration, and subsequent remyelination after 6 weeks of post-cuprizone recovery. MRI measurements were complemented with Black Gold II stain for myelin and immunohistochemical stains for associated tissue changes. Gene expression was evaluated using the Allen Gene Expression Atlas. Twenty-five C57BL/6 male mice were split into control and cuprizone groups; MRI data were obtained at baseline, after 6 weeks of cuprizone, and 6 weeks post-cuprizone. High-resolution (100 μm isotropic) whole-brain coverage magnetization transfer ratio (MTR) parametric maps demonstrated concurrent caudal-to-rostral and medial-to-lateral gradients of MTR decrease within corpus callosum (CC) that correlated well with demyelination assessed histologically. Our results show that demyelination was not limited to the midsagittal line of the corpus callosum, and also that opposing gradients of demyelination occur in the lateral and medial CC. T2-weighted MRI gray/white matter contrast was strong at baseline, weak after 6 weeks of cuprizone treatment, and returned to a limited extent after recovery. MTR decreases during demyelination were observed throughout the brain, most clearly in callosal white matter. Myelin damage and repair appear to be influenced by proximity to oligodendrocyte progenitor cell populations and exhibit an inverse correlation with myelin basic protein gene expression. These findings suggest that susceptibility to injury and ability to repair vary across the brain, and whole-brain analysis is necessary to accurately characterize this model. Whole-brain parametric mapping across time is essential for gaining a real understanding of disease processes in-vivo. MTR increases in healthy mice throughout adolescence and adulthood were observed, illustrating the need for appropriate age-matched controls. Elucidating the unique and site-specific demyelination in the cuprizone model may offer new insights into in mechanisms of both damage and repair in human demyelinating diseases.

  • In contrast to EAE, where lesion formation happens stochastically/sporadically in the spinal cord, cuprizone lesions are confined to certain topographical areas in the brain, increasing reproducibility.

    “In contrast to the EAE model where lesion formation happens stochastically/sporadically in the spinal cord, the lesions are confined to these certain topographical areas in the brain – increasing the reproducibility [189, 190].”

    From Insights and challenges on animal models for progressive multiple sclerosis (2026) · cites this paper as [189]

    The Introduction says cuprizone reliably produces demyelination in the murine brain, and the Discussion (‘Regional heterogeneity may hold the key to understanding the model’; page unavailable) describes site-specific patterns in the corpus callosum. These passages support the cuprizone portion, but they do not establish that EAE spinal-cord lesions form sporadically or that the spatial pattern itself increases reproducibility. (LLM, conf=0.86)

  • The cuprizone mouse model is a well-established demyelination model.

    “The cuprizone mouse model is a well-established demyelination model, and MRI studies demonstrated that various MRI techniques can detect white matter abnormality noninvasively (Thiessen et al. 2013; Tagge et al. 2016).”

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.
