Abstract
BACKGROUND: Gestational diabetes mellitus (GDM) is the most common metabolic complication of pregnancy. To define the altered pathway in GDM placenta, we investigated the transcriptomic profiles from human placenta between GDM and controls. METHODS: T, and senescent T cell subsets were determined by flow cytometry based on staining for specific intracellular cytokines. RESULTS: ) expression. Programmed death-ligand 1 expression in syncytotrophoblasts was also significantly increased in patients with GDM. CONCLUSION: This study demonstrated increased proinflammatory T cells, senescent T cells and immune-check point molecules in GDM placentas, suggesting that changes in senescent T cells and immune-escape signaling might be related to the pathophysiology of GDM.
