Abstract

Abstract:

The purpose of this study was to prepare a milk-derived exosome (miEVs) delivery system loaded with forsythiaside A (FTA) and kaempferol (KPF) and evaluate its effect on lipopolysaccharide (LPS)-induced bovine mammary epithelial cells (MAC-T) in vitro Effects of cell migration and related inflammatory factors in inflammation models. FTA-loaded milk-derived exosomes (FTA-miEVs) and KPF-loaded milk-derived exosomes (KPF-miEVs) were prepared by using the acetic acid method established and optimized in the early stage, and the low-temperature ultrasonic co-incubation method was usedAs well as the establishment of inflammation models, and the evaluation of the preparation effect by transmission electron microscopy (TEM) and immunoblotting (Western blot) methods, the liquid chromatography-mass spectrometry method for drug loading determination, immunofluorescence and scratch experiments to observe the effect of inflammation models on the uptake of milk-derived exosomes loaded with anti-inflammatory drugs, and the effect of cell migration in the inflammation model, enzyme-linked immunosorbent assay (ELISA) and real-time quantitative PCR (RT-qPCR) were used to verify the effects of milk-derived exosomes loaded with anti-inflammatory drugs on the secretion of related inflammatory factors and gene expression levels in inflammation models. The results showed that FTA-miEVs and KPF-miEVs both had typical exosome structures, with circular shapes and partial depressions, similar to the "saucer" structure. Both surface and internal specific marker proteins leukocyte differentiation antigen 81 (CD-81) and heat shock protein 70 (HSP70) can be expressed. The drug loading was 0.78% and 9.79%, respectively. Within 8 hours, the LPS-induced MAC-T inflammation model had a good uptake effect; At 24 h, the inhibition rates of FTA-miEVs and KPF-miEVs on cell migration in inflammation models were 608.48% and 522.88%, respectively, which were significantly higher than those of miEVs, FTA and KPF alone. It has a positive effect on interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor α (TNF-α) in models of inflammation. The secretion and gene expression levels were better than those of miEVs, FTA and KPF alone. In summary, the FTA-miEVs and KPF-miEVs drug delivery systems were successfully prepared in this experiment, and the comprehensive results showed that the anti-inflammatory effects of FTA and KPF could be improved at the same dosage, which provided a new idea for the preparation and clinical application of exosomes in drug delivery systems.
