FGF2 and neoplasm: BFGF‐modified OMVs induce high levels of anti‐BFGF autoantibodies suppressing TC‐1 and B16F10 tumor cell growth.[219] On the other hand, a variant of EGFR‐EGFRvIII‐decorated E. coil OMVs was capable of inducing a potent anti‐EGFRvIII antibody response which strongly reduced the growth of B16F10 tumor cells expressing human EGFRvIII.
