Abstract: The use of a transcriptomic signature based on HERVs expression to characterize new AML subtypes, and a method to determine to which AML subtype a patient pertains. The method includes providing relationship between the 9 AML sub-types and HERVs characterized by their specific herv_id and their relationship with one of these AML subtypes, determining from a patient cell sample HERVs expression profile, determining which of the 9 AML subtypes is the most represented based on HERV expression in the cell sample, and attributing to the patient the most represented AML subtype among the 9 AML subtypes. The method allows identifying patients with medium good or bad prognosis and treating the same with a cancer therapy against AML.

Abstract: The invention is in the field of therapy of antibody deficiencies. Inventors demonstrate for the first time in both controls and IgA-deficient patients. systemic anti-microbiota IgG responses correlate with reduced inflammation suggesting that systemic IgG responses contribute to the gut microbiota confinement. Furthermore. SIgAd-associated inflammation is inversely correlated with systemic anti-commensal IgG responses, which may thus serve as a second line of defense. Altogether, these data suggest that systemic IgG and intestinal IgA cooperate in different body compartments to limit systemic pro-inflammatory pathways. As selective IgA deficient patients harbour elevated seric anti-commensal IgG levels. these findings suggest that in selective IgA deficiency, microbiota confinement is obtained at the price of a strong inflammatory response. Accordingly. the invention relates to a composition containing immunoglobulins A (IgA). more particularly secretory IgA.

In particular, the present invention relates to CLEC-1 antagonists for promoting T cells response in a subject in need thereof.

Abstract: Disclosed is a method for obtaining a population of human Treg cells including the steps of: (a) culturing a population of human monocytes with a medium including an amount of an interleukin-34 (IL-34) polypeptide in order to obtain a population of immunosuppressive macrophages; (b) co-culturing a population of human peripheral blood mononuclear cells (PBMCs) and the population of immunosuppressive macrophages obtained at step (a).

Abstract: The present invention relates to regulatory T cell and uses thereof. By their immunosuppressive and anti-inflammatory activities, regulatory T cells play a central role in peripheral tolerance and thus critically prevent the development of autoimmune and inflammatory disorders. The inventors showed that Foxp3+CD4+ Tregs express high levels of LT?, which negatively regulates their immunosuppressive signature. The inventors have demonstrated that the adoptive transfer of Tregs previously incubated with soluble lymphotoxin-? receptor in mice protects from dextran sodium sulfate (DSS)-induced colitis. Thus, the number of cells to be injected in adoptive transfer may be reduced and a transfection or transduction step avoided, which represents a technical facilitation.

Abstract: The present invention relates to the prevention and treatment of disease like cancer. The inventors have previously characterized MELOE-1 antigen as an IRES dependent, melanoma specific translation product from a lncRNA mainly transcribed in the melanocytic lineage. MELOE-1 contains numerous class II epitopes and one HLA-A*0201-restricted CD8 epitope eliciting a frequent repertoire of high avidity T cells. They designed various synthetic long peptide (SLPs) comprising a CD4 epitope coupled to the CD8 epitope by a serie of linkers of 4 to 6 aa and studied the efficacy of T cell clone activation by SLP-loaded DC in vitro. Particularly, they evaluated the ability of a few selected SLPs to stimulate specific T cells proliferation of PBL from healthy donors in vitro and finally, they explored the vaccination potential of their best SLP candidate in vivo in an HLA*A0201/HLA-DRB0101 transgenic mouse.

Abstract: Inflammation is a prominent feature of ischemia-reperfusion injury (IRI) characterized by leukocyte infiltration and renal tubular injury. However, the signals that initiate these events remain poorly understood. The inventors identify the nuclear alarmin interleukin (IL)-33 as an initiation factor of tissue injury and also as a major amplification factor of the innate immune response triggered by experimental kidney ischemia-reperfusion in mice. In mice lacking IL-33, IRI is reduced, as attested by early decreased tubular cell injury, and by subsequent decreased infiltration of IFN-?/IL-17A-producing neutrophils and preservation of renal functions. These findings led the inventors to propose that endogenous IFN-33 contributes to kidney IRI by promoting iNKT cell recruitment and cytokine production, resulting in neutrophil infiltration and activation at the injury site. Accordingly, the present invention relates to antagonists of IL-33 for use in methods for preventing ischemia reperfusion injury in an organ.
