Hierarchic clustering of genes regulated in both DCs and Mϕs following pathogen exposure. Genes were arranged according to their gene expression pattern (fold change) by hierarchic clustering, with the genes arranged vertically and the pathogens (in replicate) arranged horizontally for DCs (left side) and Mϕs (right side). Red indicates gene induction; green, gene repression. Analysis was done for DCs and Mϕs independently. The expression profile of 4 major clusters (yellow outline) is also plotted for both DCs and Mϕs. The red and green lines in each graph (in middle) represent the 2-fold change values; blue lines represent the average fold-change values.
