The small GTPase ARF6 is known to regulate endocytosis and recycling of plasma membrane proteins. Here the authors show that tumourintrinsic ARF6 promotes an immunosuppressive microenvironment that accelerates melanoma progression but that is vulnerable to immune checkpoint blockade, mechanistically linked to ARF6-dependent recycling of interferon-gamma receptors in tumour cells.
