Exosomes were isolated, and the concentration and size distribution were assessed. The exosome surface markers CD9, CD63, CD81, HSP70, and TSG101 were detected by Western blot. The exosome proteins were evaluated by quantitative proteomics using a tandem mass tag (TMT). All the identified proteins were submitted to the Weighted Gene Co-Expression Network Analysis (WGCNA), GO function, and KEGG pathway analysis. A protein-protein interaction network (PPI) was utilized to identify hub proteins with the Cytohubba plugin of Cytoscape.\u0000\u0000\u0000\u0000The exosomes were round or oval vesicular structures at a diameter range of 100-200 nm, and the size distribution was standard and consistent. Exosome surface markers CD9, CD63, CD81, HSP70, and TSG101 were detected. 444 out of 450 proteins were mapped with gene names. A brown module containing 71 proteins was highly linked with the 12 h phenotype and was predominantly concentrated in lipoprotein and complement activation.

The present study aimed to determine whether\u0000vitronectin levels are altered in TB patients compared to healthy humans.\u0000\u0000\u0000\u0000Twenty-four laboratory-confirmed tuberculosis patients (pulmonary TB -8, extrapulmonary-8 and HIV-TB dual infected -8) and eight healthy individuals were included in this study.\u0000The quantitative detection of vitronectin in serum-derived exosomes of study participants was performed using a sandwich enzyme-linked immunosorbent assay. Measured concentrations of vitronectin were compared with the demographic variables of the study participants and between the study\u0000groups. The Mann–Whitney U unpaired test was used in statistical analysis, and the p-value < 0.05\u0000was considered statistically significant.\u0000\u0000\u0000\u0000Vitronectin was detected in serum-derived exosomes of all study participants. The demographic characteristics (gender, age, smoking and alcohol consumption habit, history of cough, and\u0000weight loss) were not significantly correlated with the vitronectin concentrations of the study participants (p-value> 0.05). The level of vitronectin was higher in patients with pulmonary TB (778.54 ng/l)\u0000and extra-pulmonary-TB patients (773.04 ng/l) while lower in HIV-pulmonary TB dual-infected patients (354.86 ng/l) as compared to healthy humans (456.20ng/l).
