In another study, this group observed increased production of interleukin (IL)-2, interferon (IFN)-γ and tumor necrosis factor (TNF)-α by peripheral blood mononuclear cells (PBMCs) in preeclampsia and, interestingly, positive correlations between mean blood pressure and concentrations of Th1 cytokines [10]. The gene discussed is IL2; the disease is preeclampsia.
