Oxysterols significantly increased the production of proinflammatory cytokines, interleukin\u20101\u03b2, regulated on activation, normal T\u2010cell expressed and secreted and macrophage migration inhibitory factor in ex vivo cultured PBMCs. Increased levels of reactive oxygen species (ROS) were also detected along with increased phosphorylation of the p38 and JNK.
