  • 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.

  • Patent number: 11230602
    Abstract: The description concerns humanized antibodies directed against the extracellular domain of the alpha chain of the receptor for interleukin-7 (IL-7), especially against the receptor for human IL-7 expressed on human cells (also designated human IL-7Ralpha or IL-7Ra or CD127) and which do not interfere with the IL-7 or TSLP signaling pathways. The antibodies described do not have an antagonistic effect on the IL-7 receptor, but may still present cytotoxic activity against CD127 positive cells. In a particular embodiment, the antibody does not have an agonist effect on the IL-7 receptor.

  • Publication number: 20200362300
    Abstract: The invention relates to methods and preparations for sorting out T effector cells from human leukocytes using anti-CD127 antibodies. Accordingly the invention relates to the use of anti-CD127 antibodies enabling discriminative depletion of subpopulations of Tregulatory cells expressing CD127+ at low levels in a population of human T lymphocytes in order to enable the use of the recovered selected cell preparations comprising essentially Teffector cells as lymphocytes and preferably devoid of Tregulatory cells, for improved efficacy in particular when administered to a patient for therapy.

  • Publication number: 20190382497
    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.
