Abstract: The invention discloses a method for selecting a human patient for CD73 antagonist therapy, preferably immunotherapy, comprising the step of determination in a patient's biological sample, that lymphocytes, preferably CD4+ T cells, express CD73, wherein, upon a determination that lymphocytes, preferably CD4+ T cells, express CD73 in patient's biological sample, the patient is declared sensitive to immunotherapy using an antagonist of CD73, preferably an anti-CD73 antibody. Combined therapy with immunotherapy against an inhibitory ICP and/or with a chemotherapeutic agent sensitive to MDR1 exclusion activity is proposed.

Abstract: The present invention relates to a method making it possible to identify the patients, from among those affected by a given solid cancer, that have increased risk of premature death. Said method is based on the ex vivo analysis of the lymphocytic diversity of the patients on the basis of a biological sample containing lymphocytes. In fact, low lymphocytic diversity is related to a poor prognosis. Specifically, it is possible to set a diversity threshold, depending on the analysis technology used and the cancer affecting the patient, beyond which the life expectancy of the patient is significantly less than that, in general, of the patients affected by the same disease.

Abstract: The present invention provides novel materials and screening methods for identifying agonists and antagonists of cell receptors. Methods are disclosed for identifying agonists and antagonists using chimeric receptors comprising the extracellular ligand-binding domain of a first receptor fused with the transmembrane and intracellular domains of a second receptor containing an intracellular immunoreceptor tyrosine-based activation motif (ITAM).

Abstract: Dendritic cells play a critical role in antigen-specific immune responses. Materials and Methods are provided for treating disease states, including cancer, infectious diseases, autoimmune diseases, transplantation, and allergy by facilitating or inhibiting the migration or activation of a specific subset of antigen-presenting dendritic cells known as plasmacytoid dendritic cells (pDC). In particular, methods for treating disease states are provided comprising administration of chemokine receptor agonists and antagonists, alone or in combination with a disease-associated antigen, with or without an activating agent.
