ABSTRACT: Variation in individuals' responses to environmental factors is believed to influence susceptibility to complex diseases in humans. The genetic basis of such variation is poorly understood. We measured gene expression from resting and stimulated dendritic cells (DCs) derived from the peripheral blood of healthy individuals. We stimulated the primary DCs with E. coli lipopolysaccharide (LPS), influenza virus or the cytokine IFNβ, and associated genetic variation between individuals with the observed variation in gene expression and gene induction. We collected peripheral blood from each human donor. We isolated peripheral blood mononuclear cells by Ficoll, and magnetically sorted them for CD14+CD16- monocytes. We then differentiated the monocytes into monocyte-derived dendritic cells (MoDCs) by culturing the cells for 7 days with GM-CSF and IL-4. We stimulated the cells with E. coli lipopolysaccharide (LPS) for 2.5 hr or 5 hr, influenza (PR8 dNS1) for 10 hr, or recombinant IFN-beta for 6.5 hr. Finally, we lysed the cells and ran Nanostring on the lysates.
