Analysis of T-Lymphocyte Subsets After Phytohemagglutinin Stimulation in Normal and Type 1 Diabetic Mothers and Their Infants

1992

Our aim was to investigate the immunological status of diabetic pregnancy, which is an overlap of diabetic immunity abnormalities and the immunological modifications normally occurring during pregnancy. METHOD: We studied lymphocyte subpopulations and lymphokine production, after 96 h of phytohemagglutinin (PHA) stimulation, from normal and Type I diabetic pregnant women at delivery time and from the respective cord blood. RESULTS: Peripheral blood mononuclear cells (PBMC) from both normal and Type I diabetic mothers showed an increase in CD8+ and a decrease in CD4+ cells compared to the respective cord blood mononuclear cells (CBMC). Moreover, Type I PBMC showed a lower number of “activate…
