Fig. 4From: Mesenchymal stromal cell-derived extracellular vesicles attenuate lung ischemia-reperfusion injury and enhance reconditioning of donor lungs after circulatory deathMSCs and EVs inhibit macrophage and iNKT cell activation after HR. a-b MH-S (alveolar macrophages) cells were exposed to hypoxia/reoxygenation (HR) and demonstrated a significant increase in HMGB1 and TNF-α production compared to normoxia (Norm) which was significantly attenuated by treatment with MSCs or EVs. c Similarly, HR-exposed iNKT cells produced increased levels of IL-17 compared to normoxia which was significantly attenuated by treatment with MSCs or EVs. n = 5/group; *, p < 0.05 vs. allBack to article page
