2.11. Statistical analyses
Statistical analyses were performed using SPSS statics 19 (IBM). Numbers for every experiment are given in the figure legends and refer to the number of every individual mouse used in the respective group. All the data were expressed as the means ± SEM and were analyzed using ANOVA with an additional Tukey-Kramer post-hoc test. Differences with Pvalues < 0.05 (*) or < 0.01 (**) were considered significant. Assessment of significance was only done for numbers ≥ 5 unless for the animal experiments, when
only some groups had lower sample sizes (Figures 2e and 4b).
