Conventional dendritic cells require IRAP-Rab14 endosomes for efficient cross-presentation.
Dendritic cells (DCs) use cellular pathways collectively referred to as cross-presentation to stimulate CD8(+) T cells with peptide Ags derived from internalized, exogenous Ags. We have recently reported that DCs rely on aminoterminal trimming of cross-presented peptides by insulin-responsive aminopeptidase (IRAP), an enzyme localized in a regulated endosomal storage compartment. Considering a ...

متن کاملIRAP identifies an endosomal compartment required for MHC class I cross-presentation.
Major histocompatibility complex (MHC) class I molecules present peptides, produced through cytosolic proteasomal degradation of cellular proteins, to cytotoxic T lymphocytes. In dendritic cells, the peptides can also be derived from internalized antigens through a process known as cross-presentation. The cellular compartments involved in cross-presentation remain poorly defined. We found a rol...
متن کاملDendritic cells require the NF-kappaB2 pathway for cross-presentation of soluble antigens.
NF-kappaB-inducing kinase (NIK) is responsible for activation of the non-canonical p100 processing pathway of NF-kappaB activation. This kinase has been shown to be critical for activation of this pathway after signaling through several TNF family members including CD40. The functional importance of this pathway in CD40 and TLR-induced dendritic cell (DC) differentiation was studied in vivo in ...
متن کاملWhole lymphoma B cells allow efficient cross-presentation of antigens by dendritic cells.
BACKGROUND In order to compensate for the paucity of defined tumor antigens (Ag) in non-Hodgkin's lymphomas, a promising approach might be the use of whole tumor cells as a source of tumor Ag to pulse antigen-presenting cells (APC). However, it is not presently known how the tumor cells should be delivered to APC to optimize the cross-presentation of tumor Ag to anti-tumor CD8 T cells. We aimed...
