Figure 2

Functional groups of genes with maximal differences in expression levels between resting NK cells (column1) and NK cells after 2, 8 or 24 hours (colums 2,3 & 4 respectively) of IL-2 activation are shown. The color change in each row represents the gene expression relative to the median across the samples and values are visualized according to the scale bar that represents the expression fold difference (log2) relative to the median. A) Cytolytic pathway, B) Cytokines, chemokines and their receptors, and C) Secretory signature.
