Then, plasma exosomes from SLE patients were extracted, and the accuracy of differential expression and functional enrichment analysis was preliminarily verified.

Through differential expression analysis of the pulbilic data and subsequent qPCR validation, we observed that miR-20b-5p is overexpressed in plasma exosomes of SLE patients, whereas miR-181a-2-3p is downregulated. Then functional enrichment analysis revealed that these differential miRNAs primarily regulate processes such as apoptosis, autophagy, and inflammation. Then, flow cytometry analysis conducted after co-incubation of plasma exosomes and peripheral blood mononuclear cells confirmed that exosomes can indeed regulate apoptosis. And plasma exosomes can successfully enter HK2 cells without affecting cell activity. In addition, plasma exosomes promote HK2 cell apoptosis and autophagy. Overexpression of miR-181a-2-3p could inhibit HK2 cells apoptosis and upregulate the expression of bcl2, and beclin1. At the same time, a trend towards increased apoptosis rates was observed in HK2 overexpressed miR-20b-5p, although the difference did not reach statistical significance.
