Heat map displaying hierarchical clustering results from microarray expression data of genes involved in the IFN system (IFNs, IRFs, ISGs…).

All the experimental groups, including the corresponding controls (PBS 8 h and PBS – MEM 8 h), were included in the analysis. Different genes are represented in different rows, and different experiments in different columns. Raw expression values are represented as a color scale from red for lower expressions to green for higher expressions.
