Antigen Presentation by Dendritic Cells In Vivo
Dendritic cells (DC) are heterogenous, comprising several subpopulations of migratory and lymphoid-organ-resident types. Recent studies addressing the role of each subset in antigen presentation in vivo have revealed a complex division of labor within the DC network. In addition to CD8(+) DC, migratory lung or dermal DC can cross-present antigen in vivo. Migratory DC also transport to the lymph...
متن کاملA critical role for Syk protein tyrosine kinase in Fc receptor-mediated antigen presentation and induction of dendritic cell maturation.
Dendritic cells (DCs) are the only APCs capable of initiating adaptive immune responses. The initiation of immune responses requires that DCs 1) internalize and present Ags; and 2) undergo a differentiation process, called "maturation", which transforms DCs into efficient APCs. DC maturation may be initiated by the engagement of different surface receptors, including certain cytokine receptors ...
متن کاملHarnessing Dendritic Cells for Tumor Antigen Presentation
Dendritic cells (DC) are professional antigen presenting cells that are crucial for the induction of anti-tumor T cell responses. As a consequence, research has focused on the harnessing of DCs for therapeutic interventions. Although current strategies employing ex vivo-generated and tumor-antigen loaded DCs have been proven feasible, there are still many obstacles to overcome in order to impro...
متن کاملExtracellular antigen processing and presentation by immature dendritic cells.
In antigen presentation to CD4(+) T cells, proteins are degraded to peptide fragments and loaded onto class II MHC molecules in a process involving the peptide exchange factors H-2M (murine) or HLA-DM (human). In many antigen-presenting cells these processes occur in intracellular endosomal compartments, where peptides are generated and loaded onto class II MHC proteins for subsequent transport...
متن کاملCeramide Inhibits Antigen Uptake and Presentation by Dendritic Cells
Ceramides are intramembrane diffusible mediators involved in transducing signals originated from a variety of cell surface receptors. Different adaptive and differentiative cellular responses, including apoptotic cell death, use ceramide-mediated pathways as an essential part of the program. Here, we show that human dendritic cells respond to CD40 ligand, as well as to tumor necrosis factor-alp...
