The distribution of gene expression.

<p>The ‘x’ axis represents Log fold-change of differentially expressed genes. The ‘y’ axis represents number of genes. Red region represents genes with expression within 4-fold change; green and blue regions represent genes with more than 4-fold change either up or down regulated, respectively. Library pairs: A, resting Vγ1⁺ vs activated Vγ1⁺ γδ T cells; B, resting Vγ4⁺ vs activated Vγ4⁺ γδ T cells.
