| Outline of Final Research Achievements |
Circulating extracellular vesicles (EVs) in plasma have been shown to mediate important inter-cellular communications in the pathogenesis of several disorders. EVs express not only cell adhesion molecules that regulate target specificities but also immune checkpoint molecules that suppress lymphocyte activation and proliferation. However, the roles of these molecules on EVs in systemic inflammatory response syndrome (SIRS) and sepsis remain elusive. In order to clarify this issue, we measured the EV expression of cell adhesion molecules and immune checkpoint molecule ligands using immunofluorescent flow cytometry on EVs immobilized on beads. We found that these molecules might differ in SIRS (n=27) and sepsis(n=27), compared with healthy controls (n=18).
