(A) Effects of exosomes on the apoptosis of BV2 microglia by Western blot. (B) Bax, (C) Caspase 9, (D) Caspase 3, and (E) Bcl-2 relative level to β-actin in BV2 microglia. Levels of apoptotic factors (F) Bax, (G) Caspase 3, and (H) Caspase 9 by immunofluorescence. Scale bar = 50 μm. *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
