Conformational variation of surface class II MHC proteins during myeloid dendritic cell differentiation accompanies structural changes in lysosomal MIIC.

Dendritic cells (DC), uniquely among APC, express an open/empty conformation of MHC class II (MHC-II) proteins (correctly folded molecules lacking bound peptides). Generation and trafficking of empty HLA-DR during DC differentiation are investigated here. HLA-DR did not fold as an empty molecule in the endoplasmic reticulum/trans-Golgi network, did not derived from MHC/Ii complexes trafficking ...

Monocyte-derived dendritic cells represent a transient stage of differentiation in the myeloid lineage.

Cultivation of human peripheral blood monocytes with granulocyte/macrophage colony stimulating factor (GM-CSF) and IL-4 facilitates generation of strongly antigen-presenting dendritic cells (DC). These monocyte-derived DC (mdDC) were used here to further delineate differentiation pathways in the myeloid lineage. Incubation of mdDC with TNF or soluble CD40L led to enhanced MHC and accessory surf...

A lysosomal targeting signal in the cytoplasmic tail of the beta chain directs HLA-DM to MHC class II compartments

In human B cells, class II molecules of the major histocompatibility complex (MHC-II) accumulate in an endosomal/lysosomal compartment, the MIIC, in which they may encounter and bind peptides. An additional molecule required for MHC-II peptide binding, HLA-DM (DM), has also been localized to the MIIC. Neither the relationship of the MIIC to the endosomal system nor the mechanisms by which DM lo...

CD1 molecules efficiently present antigen in immature dendritic cells and traffic independently of MHC class II during dendritic cell maturation.

Upon exposure to Ag and inflammatory stimuli, dendritic cells (DCs) undergo a series of dynamic cellular events, referred to as DC maturation, that involve facilitated peptide Ag loading onto MHC class II molecules and their subsequent transport to the cell surface. Besides MHC molecules, human DCs prominently express molecules of the CD1 family (CD1a, -b, -c, and -d) and mediate CD1-dependent ...

Antigen capture and major histocompatibility class II compartments of freshly isolated and cultured human blood dendritic cells

Dendritic cells (DC) represent potent antigen-presenting cells for the induction of T cell-dependent immune responses. Previous work on antigen uptake and presentation by human DC is based largely on studies of blood DC that have been cultured for various periods of time before analysis. These cultured cells may therefore have undergone a maturation process from precursors that have different c...
