摘要:
The present invention provides antibodies directed against ICOS or a derivative thereof which neutralize ICOS engagement on Treg by inhibiting the fixation between ICOS and ICOS-L and abrogate proliferation of Treg induced by plasmacytoid dendritic cells. The present invention further provides antibodies directed against ICOS or a derivative thereof which induce IL-10 and IFNγ production, induce CD4+ T cells proliferation, reduce Tconv proliferation, and increase the immunosuppressive function of Treg.

摘要:
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.
摘要:
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.
摘要:
Nucleic acids encoding various proteases, from a mammal, reagents related thereto, including specific antibodies, and purified proteins are described. Methods of using said reagents and related diagnostic kits are also provided.
摘要:
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).
摘要:
Dendritic cells play a critical role in antigen-specific immune responses. Materials and methods are provided for treating disease states, including cancer and autoimmune disease, by facilitating or inhibiting the migration or activation of antigen-presenting dendritic cells. In particular, chemokines are used to initiate, amplify or modulate an immune response. In one embodiment, chemokines are used to attract dentritic cells to the site of antigen delivery. An increase number of dendritic at the site of antigen delivery means more antigen uptake and a modified immune response.
摘要:
Polynucleotides encoding various dendritic cell specific proteins from a primate are provided. Uses of purified sequences are also disclosed, including producing related reagents, e.g., specific antibodies, and purified proteins. Methods of using these reagents and related diagnostic kits are also described.
