This article explores the expression and clinical significance of two immunomodulatory molecules, Indoleamine 2,3-Dioxygenase (IDO) and Human Leukocyte Antigen-G (HLA-G), in GDM. It is indicated that the increased activity of IDO during pregnancy helps protect the fetus from maternal immune system attacks, but under GDM conditions, it leads to a reduction in IDO activity. HLA-G maintains immune balance between mother and fetus by inhibiting immune cell function, but GDM causes a decrease or even variation in the levels of soluble HLA-G in the serum. The reduction in IDO activity and changes in HLA-G expression suggest impaired immune tolerance. The combined detection of these two molecules can provide crucial information for the early diagnosis, monitoring, and treatment evaluation of GDM.展开更多

Accumulating evidence suggests a significant association between ferroptosis and the pathogenesis of pregnancy-related disorders. Studies have shown that inhibiting ferroptosis may offer therapeutic benefits in managing these conditions. This review aims to elucidate molecular mechanisms underlying ferroptosis and to summarize recent advancements in understanding its role in pregnancy-related diseases, thereby providing novel insights for the diagnosis and treatment of such disorders.展开更多
