  • Patent number: 11884723
    Abstract: The invention is in the field of immunotherapy. The present invention provides antibodies useful in therapeutic and diagnostic applications targeting human SIRPa, said antibodies enhancing the cross-presentation of antigens to T cells. The invention also provides antibodies against specific isoforms of SIRP a and able to disrupt the interaction between those isoforms of SIRP a and human CD47 for use in treating or preventing a disease, or diagnostic applications, and methods for producing and/or selecting anti-human SIRPa antibodies that bind with different affinities to various isoforms of human SIRP members.

  • Publication number: 20230340133
    Abstract: The invention relates to antibodies directed against CD127, the alpha chain of the interleukin 7 (IL-7) receptor IL-7R), and which have antagonist properties for IL-7-IL-7R interaction, may present cytotoxic activity against CD127 positive cells but do not increase the maturation of dendritic cells (DCs) induced by TSLP, a cytokine also using CD127 as part of its receptor. Alternatively, or in addition, these antibodies do not induce the internalization of CD127 and/or inhibit the IL7-induced internalization of CD127.

  • Publication number: 20220298259
    Abstract: The present disclosure concerns the use of an anti-SIRPa compound able to inhibit the polarization of anti-inflammatory M2-type macrophages and/or favors pro-inflammatory M1-type macrophages. In a preferred embodiment, such compound is used to treat cancer. Interestingly, this disclosure allows to treat cancer through an indirect pathway involving the immune system.

  • Publication number: 20220281993
    Abstract: The present invention pertains to the field of immunotherapy. More specifically, the present invention provides a method for differentiating myeloid-derived suppressor cells (MDSC) into non suppressive cells, by administering a compound blocking the interaction between SIRPa and CD47 to a patient in need thereof, in order to reduce MDSC-induced immunodepression and consequently allow appropriate immune responses in cancers, infectious diseases, vaccination, trauma, autoimmune diseases, chronic inflammatory diseases and transplantation.

  • Publication number: 20220281983
    Abstract: The present invention relates to methods for promoting T cells response. The inventors examined the expression and function of CLEC-1 in human DCs and demonstrated for the first time a cell-surface expression. They investigated its functional role following triggering on orchestration of T-cell responses. The inventors showed in vitro and in vivo with CLEC-1 deficient rats and rat CLEC-1 Fc fusion protein that disruption of CLEC-1 signalling enhances in vitro Th17 activation and in vivo enhances T cell priming and Th17 and Th1 activation. In particular, the present invention relates to CLEC-1 antagonists for promoting T cells response in a subject in need thereof.
