Fig 6. OMVs associate with mitochondria.

Fig 6

(A, B and C) Bone marrow-derived macrophages (BMDMs) were treated with purified N. gonorrhoeae OMVs for 24 hours and imaged by transmission electron microscopy by negative staining and (C) 10 nm-gold conjugated antibodies against PorB. (D) Crude mitochondria (P) and cytoplasmic fractions (S) were obtained from OMV-treated BMDMs and analyzed for PorB and BamA and mitochondria (Tim23, Tom40 and F1β) and cytosolic (GAPDH) markers by immunoblot analysis after semi-native gel electrophoresis. (E) Mitochondria-enriched fractions were incubated with purified OMVs or PBS and subsequent supernatant (S) and pellet (P) fractions were analyzed by immunblotting with anti-PorB, BamA and Tim23 antibodies after SDS gel electrophoreses.
