When genotype differences between the WT and GFAP-IL6 mice were analyzed, the ataxia score of the 6- (2.9 ± 0.4) and 14- (2.4 ± 0.54) -month-old GFAP-IL6 animals proved to be significantly worse than their WT littermates (0.9 ± 0.34 for 6 months and 1.2 ± 0.46 for 14 months, respectively) (Figure 5B). This evidence concerns the gene GFAP and cerebellar ataxia.
