EVIR: chimeric receptors that enhance dendritic cell cross-dressing with tumor antigens

Nat Methods. 2018 Mar;15(3):183-186. doi: 10.1038/nmeth.4579. Epub 2018 Jan 22.

Abstract

We describe a lentivirus-encoded chimeric receptor, termed extracellular vesicle (EV)-internalizing receptor (EVIR), which enables the selective uptake of cancer-cell-derived EVs by dendritic cells (DCs). The EVIR enhances DC presentation of EV-associated tumor antigens to CD8+ T cells primarily through MHCI recycling and cross-dressing. EVIRs should facilitate exploring the mechanisms and implications of horizontal transfer of tumor antigens to antigen-presenting cells.
