Glycan modification of antigen alters its intracellular routing in dendritic cells, promoting priming of T cells
Antigen uptake by dendritic cells and intracellular routing of antigens to specific compartments is regulated by C-type lectin receptors that recognize glycan structures. We show that the modification of Ovalbumin (OVA) with the glycan-structure Lewis(X) (Le(X)) re-directs OVA to the C-type lectin receptor MGL1. Le(X)-modification of OVA favored Th1 skewing of CD4(+) T cells and enhanced cross-...
متن کاملFibroblast and T cells conditioned media induce maturation dendritic cell and promote T helper immune response
Dendritic cells (DCs) induce pathogen-specific T cell responses. We comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), PHA activated T cells (T cell conditioned medium), and mixture of fibroblast & PHA activated T cells (FCM-TCCM) conditioned media on maturation of DCs. Monocytes were cultured with GM-CSF and IL-4 for five days. ...
متن کاملMesenchymal stem cells impair in vivo T-cell priming by dendritic cells.
Dendritic cells (DC) are highly specialized antigen-presenting cells characterized by the ability to prime T-cell responses. Mesenchymal stem cells (MSC) are adult stromal progenitor cells displaying immunomodulatory activities including inhibition of DC maturation in vitro. However, the specific impact of MSC on DC functions, upon in vivo administration, has never been elucidated. Here we show...
متن کاملCD8+ T Cell Priming by Dendritic Cell Vaccines Requires Antigen Transfer to Endogenous Antigen Presenting Cells
BACKGROUND Immunotherapeutic strategies to stimulate anti-tumor immunity are promising approaches for cancer treatment. A major barrier to their success is the immunosuppressive microenvironment of tumors, which inhibits the functions of endogenous dendritic cells (DCs) that are necessary for the generation of anti-tumor CD8+ T cells. To overcome this problem, autologous DCs are generated ex vi...
متن کاملdendritic 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...
