Cover Story: The mechanisms leading to anti-PD-L1/PD-1 resistance in cancer remain elusive. Exosomes (extracellular nanovesicles secreted by almost all cells, including tumor cells) are key actors in this resistance. Exosomes released by tumor cells (TEXs) express different immune checkpoints and disseminate immune-suppressive properties. Their impact is mediated by a wide range of actions, exerting an overall effect on immunity by inactivating immune cells even before they get to the tumor. Much remains to be discovered to understand the molecular mechanisms through which TEXs modulate resistance to immunotherapies. Blocking TEXs bearing immune checkpoints might be a way to counteract PD-L1/PD-1 blockade resistance. Therefore, TEXs have potential clinical interest as new targets for immunotherapy and as biomarkers in liquid biopsies. View this paper
