Probe set ID = The probe set ID represents the unique probe set identifier of the Affymetrix mouse genome 430 2.0 array.

K-means cluster = The number refers to the respective cluster of genes with a similar expression pattern in k-means cluster analysis as displayed in Fig.5-3 and Table 5-I.

q-value = Significant differential gene expression between TMEV-infected and mock-infected mice in the time course of TME was determined employing the spline-based method embedded in EDGE. Additionally, q-values were calculated independently for each time point (14, 42, 98, 196 dpi). A time course q-value of ≤ 0.01 was selected to designate significant changes in gene expression, and simultaneously limit the maximally allowed false discovery rate to 1%.

Fold change = The fold change was calculated as the ratio of the inverse-transformed arithmetic means of the log2-transformed expression values of TMEV-infected versus mock-infected mice. Down-regulations are shown as negative reciprocal values.

Supplemental table 5-2: Results of the functional annotation clustering of all 1001 differentially expressed genes. The table shows the functional annotation clusters containing more than 50% significantly enriched gene ontology terms at a false discovery rate of 1.0%.

Functional annotation cluster = Groups of functionally related gene ontology terms derived by DAVIDs functional annotation clustering tool with medium stringency settings. Only those functional annotation clusters containing ≥ 50% significantly enriched gene ontology terms at a false discovery rate of 1.0% were selected.

Gene ontology terms = Terms of the category “biological process” from the gene ontology database.

Number of genes = Number of genes out of the 1001 differentially expressed genes between the TMEV-infected and mock-infected mice associated with the respective gene ontology term.

FDR = False discovery rate of significant enrichment for the respective gene ontology term.

Categories = Terms of the category “biological process” from the gene ontology database.

Category size = Number of genes out of the 19238 unique official gene symbols of the Affymetrix mouse genome 430 2.0 array associated with the respective category.

Median category p-value = The median p-value of the respective category is used for ranking the categories and should not be used as a metric of statistical significance. According to Eichler et al. (2007), p-values < 0.04 represent possible biological associations between the category and the biology represented by the signature file.

FDR = False discovery rate of the respective category for the probability of observing any other category with an association to demyelination that is more significant by chance.

Top 5 genes and gene importance values = A variable length list containing the genes and their corresponding median importance scores. According to Eichler et al. (2007), genes with importance scores that are greater than 0.8 have represent possible biological importance, although that can vary between different data sets.
