Figure 2.

Heat map showing the differential expression patterns of LPS-stimulated genes. N_avg, (N+L) _avg and (T+L) _avg are as described in Figure 1. N_abs was introduced to distinguish the patterns clearly and it is equal to one. The rationale was that the fold change is >1 for both classes of genes in the N+L phenotype, and <1 for pro-inflammatory and >1 for the antibacterial class genes in the T+L phenotype. Only a subset of the pro-inflammatory genes is shown.
