  • Patent number: 11905253
    Abstract: The present invention relates the field of reducing CD95-mediated cell motility in a subject, in particular for their use in the reduction of CD-95 mediated cancer cell motility, the reduction of CD95-mediated lymphocyte motility and/or B cell maturation, or the treatment of B-cell tumors, in a subject. The inventors identified a novel family of compounds having the ability to disrupt CD95/PLC?1 interaction and to neutralize the CD95-mediated calcium signaling pathway and cell migration in human peripheral blood lymphocytes (PBLs) and Th17 cells.

  • Patent number: 10556941
    Abstract: The present invention relates to polypeptides and uses thereof for reducing CD95-meditated cell motility. In particular, the present invention relates to a polypeptide having an amino acid sequence having at least 70% of identity with the amino acid sequence ranging from the amino-acid residue at position 175 to the amino-acid residue at position 191 in SEQ ID NO:1.

  • Publication number: 20190350907
    Abstract: The present invention relates to a method for reducing CD95-mediated cell motility. To identify chemicals disrupting CD95/PLC?1 interaction, the inventors screened a chemical library of EMA/FDA-approved molecules against a protein-fragment complementation assay (PCA) monitoring the binding of CD95 to PLC?1. From this screen, five chemical molecules showed the ability to disrupt CD95/PLC?1 interaction and to neutralize the CD95-mediated calcium signaling pathway and cell migration in human peripheral blood lymphocytes (PBLs) and Th17 cells. Thus, the present invention relates to a method for reducing CD95-mediated cell motility, comprising administering the subject with at least one compound selected from the group consisting of HIV-protease inhibitors (e.g. ritonavir), diflunisal, anethole, rosiglitazone and daunorubicin.

  • Patent number: 9851358
    Abstract: The present invention relates to methods and pharmaceutical compositions for preventing or reducing metastatic dissemination (i.e. reducing motility of cancer cells). In particular, the present invention relates to a method for preventing or reducing metastatic dissemination (i.e. reducing motility of cancer cells) in a subject suffering from a cancer comprising the steps consisting of i) determining the expression level of at least one biomarker selected from the group consisting of soluble CD95L and EMT promoting factors in a sample obtained from the subject, ii) comparing the expression level determined at step i) with a predetermined reference value and iii) administering the subject with a therapeutically effective amount of C16-ceramide or derivatives such as C16-sphingomyelin and C16-glycosphingolipids when the expression level determined at step i) is higher than the predetermined reference value.
