ONLINE COVER Make Way for T Cells. Tumor-associated blood vessels often display a chaotic and aberrant architecture that limits the extravasation of antitumoral T cells (top). These vascular abnormalities are induced, at least in part, through the proangiogenic actions of vascular endothelial growth factor A (green dots) and angiopoietin 2 (yellow dots). Schmittnaegel et al. show that a monoclonal antibody against both factors, termed A2V (purple), normalizes the tumor vascular network to facilitate the arrival of T cells that produce the immune-activating molecule interferon-γ (silver dots, bottom). These findings illustrate the immunostimulatory potential of antiangiogenic drugs and encourage their application as conditioning regimens for improving cancer immunotherapy.
