IL6 and gestational diabetes: Thus, we first showed that an altered placental lipid metabolism is associated with enhanced maternal cytokines levels (essentially IL-6) present in serum of GDM women in late gestation, including a diminished placental fatty acid β-oxidation capacity and an excess FFA accumulation in the form of TGs, which may limit the amount of maternal lipid transferred to the fetus across of the placenta in diabetic pregnancies.
