Metabolomic analyses of differential metabolites in plasma exosomes from SLE patients. A OPLS-DA score plots from metabolomics analysis comparing plasma exosomal profiles between: SLE vs NC, N-SLE vs NC, and SLE vs N-SLE. B Number of significantly different metabolites identified in each comparison group. C-E Heatmaps displaying significantly different metabolites between groups: (C) SLE vs NC, (D) N-SLE vs NC, (E) SLE vs N-SLE (Screening criteria: VIP ≥ 1, |FC| ≥ 1.5, and p ≤ 0.05). F-H Bubble plots: KEGG pathway enrichment analysis of differentially expressed metabolites: (F) SLE vs NC, (G) N-SLE vs NC, (H) SLE vs N-SLE
