Gene expression profiles obtained from dermal fibroblasts stimulated with different strains of <i>B. burgdorferi</i> ss.

<p>(A) Venn diagram of genes significantly up-regulated (↑) or down-regulated (↓) after fibroblast stimulation with <i>Borrelia</i>, and compared with unstimulated fibroblasts. (B) Number of genes differentially expressed during fibroblast stimulation with <i>Borrelia</i>. The bars reflect the number of up-regulated genes (+) and down-regulated genes (-) for each strain. The light dotted areas correspond to gene expression changes of 1.7–5.0-fold, the grey hatched areas correspond to changes of 5.0–20.0-fold and black areas to changes ≥20.0-fold.
