Study summary Full title Ultrasonication of Milk Decreases the Content of Exosomes and MicroRNAs in an Exosome-defined Rodent Diet All authors Sonal Sukreet, Camila Pereira Braga, Thuy T An, Jiri Adamec, Juan Cui, Janos Zempleni Journal J Nutr Abstract Background: Bovine milk exosomes (BMEs) harbor regulatory proteins, lipids and microRNAs. Consumptio (show more...)Background: Bovine milk exosomes (BMEs) harbor regulatory proteins, lipids and microRNAs. Consumption of an exosome and RNA-depleted (ERD) diet elicited phenotypes compared to controls fed an exosome and RNA-sufficient (ERS) diet in mice. All other ingredients were identical in the diets. ERD and ERS diets were prepared by substituting ultrasonicated and non-ultrasonicated milk, respectively, for casein in the AIN-93G formulation. Objective: The objective of this study was to assess the effect of ultrasonication of milk on exosome content and bioavailability, and cargo content. Methods: Bovine milk was ultrasonicated and exosomes were isolated by ultracentrifugation (USE); controls were not ultrasonicated (NSE). Exosome count, size and morphology were assessed using a nanoparticle tracker and electron microscopy. RNAs, lipids and proteins were analyzed by RNA-sequencing and mass spectrometry. Intestinal transport, bioavailability and distribution were measured by using fluorophore-labeled USEs and NSEs in Caco-2 cells, FHs 74 Int cells and C57BL/6J mice (n = 3; age 6 - 8 weeks). Results: The exosome count was 76 ± 22% lower in USE compared to NSE (P < 0.05). Ultrasonication caused a degradation of up to 100% of microRNAs. USE and NSE contained 145 and 332 unique lipid signatures, respectively (P < 0.05). We detected total of 525 and 484 proteins in USE and NSE. The uptake of USEs decreased by 46 ± 30% and 40 ± 27% compared to NSEs in Caco-2 and FHs 74 Int cells, respectively (P < 0.05). The hepatic accumulation of USEs was 48% ± 28% lower than the accumulation of NSEs in mice (P < 0.05). Conclusions: Ultrasonication of milk depletes bioavailable BMEs in studies of Caco-2 cells, FHs 74 Int cells and C57BL/6J mice and causes a near-complete degradation of microRNA cargos.

Study summary Full title A new transgene mouse model using an extravesicular EGFP tag enables affinity isolation of cell-specific extracellular vesicles All authors Mikkel Ø. Nørgård, Lasse B.

Andersen & Per Svenningsen Journal Sci Rep Abstract The in vivo function of cell-derived extracellular vesicles (EVs) is challenging to establish since (show more...)The in vivo function of cell-derived extracellular vesicles (EVs) is challenging to establish since cell-specific EVs are difficult to isolate and differentiate. We, therefore, created an EV reporter using truncated CD9 to display enhanced green fluorescent protein (EGFP) on the EV surface. CD9truc-EGFP expression in cells did not affect EV size and concentration but enabled co-precipitation of EV markers TSG101 and ALIX from the cell-conditioned medium by anti-GFP immunoprecipitation. We then created a transgenic mouse where CD9truc-EGFP was inserted in the inverse orientation and double-floxed, ensuring irreversible Cre recombinase-dependent EV reporter expression. We crossed the EV reporter mice with mice expressing Cre ubiquitously (CMV-Cre), in cardiomyocytes (αMHC-MerCreMer) and renal tubular epithelial cells (Pax8-Cre), respectively. The CD9truc-EGFP positive mice showed Cre-dependent EGFP expression, and plasma CD9truc-EGFP EVs were immunoprecipitated only from CD9truc-EGFP positive CD9truc-EGFPxCMV-Cre and CD9truc-EGFPxαMHC-Cre mice, but not in CD9truc-EGFPxPax8-Cre and CD9truc-EGFP negative mice. In urine samples, CD9truc-EGFP EVs were detected by immunoprecipitation only in CD9truc-EGFP positive CD9truc-EGFPxCMV-Cre and CD9truc-EGFPxPax8-Cre mice, but not CD9truc-EGFPxαMHC-Cre and CD9truc-EGFP negative mice. In conclusion, our EV reporter mouse model enables Cre-dependent EV labeling, providing a new approach to studying cell-specific EVs in vivo and gaining a unique insight into their physiological and pathophysiological function.

We, therefore, created an EV reporter using truncated CD9 to display enhanced green fluorescent protein (EGFP) on the EV surface. CD9truc-EGFP expression in cells did not affect EV size and concentration but enabled co-precipitation of EV markers TSG101 and ALIX from the cell-conditioned medium by anti-GFP immunoprecipitation. We then created a transgenic mouse where CD9truc-EGFP was inserted in the inverse orientation and double-floxed, ensuring irreversible Cre recombinase-dependent EV reporter expression. We crossed the EV reporter mice with mice expressing Cre ubiquitously (CMV-Cre), in cardiomyocytes (αMHC-MerCreMer) and renal tubular epithelial cells (Pax8-Cre), respectively. The CD9truc-EGFP positive mice showed Cre-dependent EGFP expression, and plasma CD9truc-EGFP EVs were immunoprecipitated only from CD9truc-EGFP positive CD9truc-EGFPxCMV-Cre and CD9truc-EGFPxαMHC-Cre mice, but not in CD9truc-EGFPxPax8-Cre and CD9truc-EGFP negative mice. In urine samples, CD9truc-EGFP EVs were detected by immunoprecipitation only in CD9truc-EGFP positive CD9truc-EGFPxCMV-Cre and CD9truc-EGFPxPax8-Cre mice, but not CD9truc-EGFPxαMHC-Cre and CD9truc-EGFP negative mice. In conclusion, our EV reporter mouse model enables Cre-dependent EV labeling, providing a new approach to studying cell-specific EVs in vivo and gaining a unique insight into their physiological and pathophysiological function.
