IL-10 regulates the balance of an immune response between pathogen clearance and immunopathology. We show here that Mycobacterium tuberculosis (Mtb) infection in the absence of IL-10 (IL-10(-/-) mice) results in reduced bacterial loads in the lung. This reduction was preceded by an accelerated and enhanced IFN-γ response in the lung, an increased influx of(More)
Dendritic cell-derived exosomes (Dex) are small extracellular vesicles secreted by viable dendritic cells. In the two phase-I trials that we conducted using the first generation of Dex (IFN-g-free) in end-stage cancer, we reported that Dex exerted natural killer (NK) cell effector functions in patients. A second generation of Dex (IFN-g-Dex) was(More)
In the past decade, the focus of tumor biology research has been switching from the functional dissection of oncogenes and tumor suppressor genes to investigation of the cross-talk between tumor cells and their microenvironment. Tumorigenesis requires the organized assembly of cancer cells with non-malignant cells and non-cellular stroma, resembling an(More)
