Cover Story: Chronic lymphocytic leukemia (CLL) is characterized by a clonal expansion of malignant B-cells and immunological defects, including T-cell dysfunctions. This leads to severe infectious complications and inefficient tumor immune surveillance. Although direct CLL-cell–T-cell interactions have been reported, the entirety of their complex interplay is incompletely understood. Here, we show that CLL-cells secrete bioactive extracellular vesicles (EVs) that carry a plethora of immune checkpoints (ICs) contributing to these T-cell deficiencies. CLL-EVs hamper T-cell viability, proliferation, activation, and metabolism while fostering their exhaustion and the formation of regulatory subsets. The variety of ICs in CLL-EVs could represent a barrier for immunotherapies, and our findings may pave the way to improving antitumor immunity by targeting EV formation or multiple ICs simultaneously.
