Antineoplastic chemotherapies are particularly efficient when they elicit immunogenic cell death, thus provoking an anticancer immune response. Here we demonstrate that autophagy, which is often disabled in cancer, is dispensable for chemotherapy-induced cell death but required for its immunogenicity. In response to chemotherapy, autophagy-competent, but(More)
Cyclophosphamide is one of several clinically important cancer drugs whose therapeutic efficacy is due in part to their ability to stimulate antitumor immune responses. Studying mouse models, we demonstrate that cyclophosphamide alters the composition of microbiota in the small intestine and induces the translocation of selected species of Gram-positive(More)
Exosomes are nanometer sized membrane vesicles invaginating from multivesicular bodies and secreted from epithelial and hematopoietic cells. They were first described "in vitro" but vesicles with the hallmarks of exosomes are present in vivo in germinal centers and biological fluids. Their protein and lipid composition are unique and could account for their(More)
Bleomycin (BLM) is an anticancer drug currently used for the treatment of testis cancer and Hodgkin lymphoma. This drug triggers cancer cell death via its capacity to generate radical oxygen species (ROS). However, the putative contribution of anticancer immune responses to the efficacy of BLM has not been evaluated. We make here the observation that BLM(More)
BACKGROUND In HER2-overexpressing breast cancer, accumulating preclinical evidences suggest that some chemotherapies, like trastuzumab, but also taxanes, are able to trigger a T helper 1 (Th1) anticancer immune response that contribute to treatment success. T helper 1 immune response is characterised by the expression of the transcription factor T-bet in(More)
The synergistic antitumor effects of the combination therapy imatinib mesylate (IM) and IL-2 depended upon NK1.1- expressing cells and were associated with the accumulation of CD11c(int)B220(+)NK1.1(+) IFN-producing killer dendritic cells (IKDC) into tumor beds. In this study, we show that the antitumor efficacy of the combination therapy was compromised in(More)
IFN-producing killer dendritic cells (IKDC) were initially described as B220(+)CD11c(+)CD3(-)NK1.1(+) tumor-infiltrating cells that mediated part of the antitumor effects of the combination therapy with imatinib mesylate and IL-2. In this study, we show their functional dependency on IL-15 during homeostasis and inflammatory processes. Trans-presentation of(More)
Melanoma is a highly metastatic and chemoresistant tumor. Recent progress in tumor genetics led to the discovery that BRAF—coding for a mitogenic serine/threonine kinase—is mutated in approximately 40% of melanoma patients, which hence can benefit from BRAF-targeted agents. When such targeted therapies cannot be employed, most patients bearing metastatic(More)
The influence of priming and pre-existing knowledge of chemotherapy-associated cognitive complaints on the reporting of such complaints in breast cancer patients. Yarker J et al. Women's perceptions of chemotherapy-induced cognitive side affects on work ability: a focus group study. Effect of medical Qigong on cognitive function, quality of life, and a(More)
