15790784ICAM-1 on exosomes from mature dendritic cells is critical for efficient naive T-cell priming.Functional analysis using DC-derived exosomes from knock-out mice showed that MHC class II and ICAM-1 are required for mature exosomes to prime naive T cells, whereas B7.2 and MFG-E8 are dispensable. Immature dendritic cells (DCs) secrete exosomes, which transfer functional major histocompatibility complex (MHC)-peptide complexes to other DCs. Proteomic and biochemical analyses revealed that mature exosomes are enriched in MHC class II, B7.2, intercellular adhesion molecule 1 (ICAM-1), and bear little milk-fat globule-epidermal growth factor-factor VIII (MFG-E8) as compared with immature exosomes.
20529672A membranous form of ICAM-1 on exosomes efficiently blocks leukocyte adhesion to activated endothelial cells.In this report, we initially observed that human cancer cells shed mICAM-1(+)-exosomes but were devoid of vascular cell adhesion molecule-1 and E-selectin. Taken together with previous findings, our results indicate that mICAM-1 on exosomes exhibits potent immune modulatory activity. We demonstrate that mICAM-1 on exosomes retained its topology similar to that of cell surface ICAM-1, and could bind to leukocytes. While intercellular adhesion molecule-1 (ICAM-1) is a transmembrane protein, two types of extracellular ICAM-1 have been detected in cell culture supernatants as well as in the serum: a soluble form of ICAM-1 (sICAM-1) and a membranous form of ICAM-1 (mICAM-1) associated with exosomes.
21336773Exosome-loaded dendritic cells elicit tumor-specific CD8+ cytotoxic T cells in patients with glioma.Exosomes had antigen-presenting molecules (MHC-I, HSP70), tumor antigen (MAGE-1) and adherent molecule (ICAM-1).
21819704Antileukaemia immunity: effect of exosomes against NB4 acute promyelocytic leukaemia cells.NB4-derived exosomes expressed the proteins retinoic acid receptor α and interstitial cell adhesion molecule 1 and contained heat shock protein 70, as demonstrated by transmission electron microscopy and Western blotting.
