dendritic cell stimulation by ifn-β alters t cell function via modulation of cytokine secretion in diabetes type 1
during antigen capture and processing, mature dendritic cells (dc) express large amounts of peptide-mhc complexes and accessory molecules on their surface. we investigated the role of ifn-β in induction hla-g expression on the monocyte derived dc and cytokine profile in diabetes type 1. we accomplished secretary pattern and total cytokine production of the th1 cytokine (il-2, γifn) and th2 cyto...
متن کاملCostimulation modulation uncouples protection from immunopathology in memory T cell responses to influenza virus.
The rapid effector functions and tissue heterogeneity of memory T cells facilitate protective immunity, but they can also promote immunopathology in antiviral immunity, autoimmunity, and transplantation. Modulation of memory T cells is a promising but not yet achieved strategy for inhibiting these deleterious effects. Using an influenza infection model, we demonstrate that memory CD4 T cell-dri...
متن کاملReduction in CD4 Central Memory T-Cell Subset in Costimulation Modulator Abatacept-Treated Patients With Recent-Onset Type 1 Diabetes Is Associated With Slower C-Peptide Decline
We previously reported that continuous 24-month costimulation blockade by abatacept significantly slows the decline of β-cell function after diagnosis of type 1 diabetes. In a mechanistic extension of that study, we evaluated peripheral blood immune cell subsets (CD4, CD8-naive, memory and activated subsets, myeloid and plasmacytoid dendritic cells, monocytes, B lymphocytes, CD4(+)CD25(high) re...
متن کاملt-helper cell type-1 transcription factor t-bet is down-regulated in type 1 diabetes
t cells have been identified as key players in the pathogenesis of type 1 diabetes. however, the exact role of t-cell subpopulations in this pathway is presently unknown. the purpose of this study was to assess the expression pattern of two lineage-specifying transcription factors gata - 3 and t - bet , which are important in t helper type 1 (th1) and th2 cell development , respectively. gene e...
