Serum free fatty acid metabolism is dysregulated in SLE patients and correlates with exosomal FAP. A-C Correlation plots of plasma exosomal FAP levels with differential fatty acid metabolites between groups: (A) SLE vs. NC, (B) N-SLE vs. NC, (C) SLE vs. N-SLE. D Free fatty acid detection using LC-MS/MS between NC, SLE and N-SLE groups（NC group, n=11; SLE group, n=11; N-SLE group, n=13. E Correlation analyses of exosomal FAP levels with fatty acid metabolites in SLE (n=24); *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001; ns, no statistical significance
