ABSTRACT: Naturally occurring FoxP3+CD4+CD25+high regulatory T cells (Tregs) play an important role in dominant tolerance, suppressing auto-reactive CD4+CD25- T cell activity. Although Tregs from T1D subjects are functionally deficient, there is little knowledge of the molecular mechanisms that orchestrate this loss of Treg function. We observed increased apoptosis (by a novel YOPRO-1/7AAD dual staining protocol) and decreased suppression in polyclonal Tregs in the periphery from high at-risk and T1D subjects. We hypothesize that prior to and during the onset of disease, Tregs lack pro-survival signals and are caught up in a relatively deficient cytokine milieu whose effects may be detectable in the periphery. Microarray analysis was performed on un-stimulated Tregs from 12 subjects with newly diagnosed T1D and 15 healthy controls. Keywords: disease-state analysis
