iNKT cell...DC by Toll like receptor ligands (TLR-L) modulates the lipid biosynthetic pathway, resulting in enhanced recognition of CD1d-associated lipids by iNKT cells; we have clarified the mechanisms by which CD1d-restricted lymphocytes translate T cell receptor (TCR) recognition of lipids with similar group...

dendritic cellWe have electroporated these DC with melanoma antigen RNA for a cross-presentation study and showed that they express the proteins ex vivo and in vivo.

dendritic cell...of intestinal lymph DC subsets in activation of naïve and memory T cells. Two of the three DC subsets are highly potent activators of naïve CD4+ T cells, and do not appear to be constitutively suppressed in any way.

dendritic cellWe have studied the immuno-physiology of rat and mouse intestinal dendritic cells. We have used a known adjuvant, E. coli heat-labile toxin (Etx) and a potential adjuvant R-848, a small TLR7/8 ligand.

dendritic cellThe DC were matured with TLR ligand R848 and polyI:C. Using these DC, we obtained best results in our evaluation whether antigens could be rerouted from the endosomal into the cytosolic compartment by combining antigen with cell penetrating peptides to further enhance cross-presentation.

dendritic cellUsing pharmacological inhibitors, or macrophages and DC from mice carrying a null mutation in MAP kinase signalling molecule(s), we have evidence for a role of certain MAP kinases in the regulation of IL-10 and IL-12, IFN-gamma production.

-
T helper cell 1We have determined mechanisms for DC-induced Th1 development and the molecular pathways for inducing Th1 cells producing IFN-gamma solely, or Th1 cells producing IFN-gamma and IL-10, which have important implications for regulation of the immune response to eradicate pathogens with minimum pathology...

T cellTo quantify presentation of the epitopes by DC, we used bulk T cells electroporated with TCR-encoding RNA in stimulation assays.

dendritic cellSince LPS-activated DC are potent inducers of NK cell priming and lymph nodes appear to be a key place in which DC and NK cell interactions occur, we have investigated the in vivo capacity of resting and DC-primed NK cells to reach the draining lymph nodes.
-
natural killer cellWe have investigated the in vivo capacity of resting (and of DC-primed) NK cells to reach the draining lymph nodes.
-
dendritic cellWe have efficiently transfected DC with RNA encoding a functional protein (E/L-selectin), which allows entry of DC into LN from HEV. These DC rolled in vitro on sialyl-LewisX-coated slides, and in vivo, mouse E/L-selectin-transfected DC homed to LN after i.v. application.
-
dendritic cellWe used dendritic cells loaded with anti-DEC205-antigen constructs, consisting of a single-chain variable fragment (scFv) directed against DEC-205, genetically linked to different parts of the MAGE-A3 model antigen (i.e. the KKl and EVDPIGHLY peptides), in a study to compare antigen-loading strategi...

dendritic cellThese multipeptide loaded cytokine matured moDC +/- CD40L activation were used for the DERMA-ER-DC 04 trial.

dendritic cellFor a transcriptional profiling of dendritic cells, DC were stimulated with PolyI:C, pretreated or not with PP2, and microarray analysis was performed.

D1 cell...at occur at the cell surface of a maturing DC, induced by a prototypical maturation stimulus such as LPS. Results obtained from the LC-MS/MS analysis of the integral plasma membrane proteome of D1 cells stimulated for 24 hours with LPS have been compared to the results obtained from immature D1 cell...
-
T cellWe observed that ICAM-1 expression by mature DCs is critical for long-lasting contacts with CD8+ T cells, but dispensable for short-lived antigen-specific interactions. Serial brief T cell-dendritic cell contacts induced early CD8+ T cell activation, proliferation and effector CTL differentiation in...

dendritic cell...cing experiments in human monocyte-derived DCs (MDDCs) with the dual aim of generating relevant knowledge on (i) the transcriptional regulation of DC differentiation, and (ii) the safe and rationale in vitro manipulation of gene expression in DCs.

dendritic cellThe question was addressed of whether bLf, whose immunomodulant properties are now recognized, could influence MDDC differentiation/activation.
