Enriched exosomes in SLE. a The size and shape of purified exosomes were evaluated by TEM imaging. The exosomes were 50–100 nm in size (arrows) and had a lipid layer (insert). b Systemic lupus erythematosus (SLE) patients had higher serum levels of exosomes than healthy controls (HCs) by acetylcholinesterase (AChE) assay. Both exosome protein markers CD81 (c) and CD63 (d) were higher in SLE than in HC. Data are presented as the median and interquartile range. *p < 0.05, **p < 0.01
