doi: 10.1016/j.isci.2026.114718
Figure Lengend Snippet: Aurkb deficiency in microglia disrupts remyelination and oligodendrocyte density in the CPZ-induced demyelination model (A) Adult Aurkb fl/fl and Cx3cr1 CreERT2/+ Aurkb fl/fl mice (2–3 months old) were i.p. injected with TAM for 5 consecutive days. After one month, the mice were fed a 0.25% CPZ-enriched diet for 5 weeks to induce demyelination (CPZ group) or followed by a CPZ-free normal diet for an additional 2 weeks (Recovery group). The corpus callosum (CC) was analyzed by immunofluorescence (IF) and Black-Gold II myelin staining. (B and C) Representative Black-Gold II myelin staining images and quantification of myelin intensity ( n = 5 mice per genotype per group, Scale bars: 200 μm). (D–F) Representative immunofluorescence analysis and quantification of total Mbp and oligodendrocytes (Olig2 + ), and g-h) representative immunofluorescence analysis and quantification of mature oligodendrocytes (CC-1 + ) ( n = 5 mice per genotype per group, Scale bars: 50 μm). Data are presented as the mean ± SD. two-way ANOVA with Bonferroni multiple comparisons test in (C, E, F, and H); ∗∗ p < 0.01 and ∗∗∗ p < 0.001; ns, not significant compared with the Aurkb fl/fl group.
