Scatterplots showing log2-fold changes for monocytes (Mono+) compared with non-monocytes (MonoD) and PBMC at 3 and 24 h.

<p>Each point corresponds to a gene and represents its differential expression after stimulation with LPS for 3 or 24 h compared to 0 h. The lines represent the cut-off of 50% fold change. Each of the 9 regions separated by the cut-off lines per graph corresponds to a cell in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0004427#pone-0004427-t002" target="_blank">Table 2</a>.
