Patents by Inventor Laurent CHENE

Laurent CHENE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240075117
    Abstract: The present invention relates to cancer immunotherapy, in particular to sequence variants of tumor-related antigenic epitope sequences. Namely, the present invention provides a method for identification of microbiota sequence variants of tumor-related antigenic epitope sequences. Such microbiota sequence variants are useful for the preparation of anticancer medicaments, since they differ from self-antigens and, thus, they may elicit a strong immune response. Accordingly, medicaments comprising microbiota sequence variants, methods of preparing such medicaments and uses of such medicaments are provided.

  • Publication number: 20230221331
    Abstract: The present invention relates to the treatment of diseases relating to proteins of the human microbiome metasecretome and, thus, to microbiome interactions, especially microbiome-host interactions. In particular the present invention relates to a method for identification of secreted peptides and proteins of the human microbiome. The present invention also relates to methods for generating a database of human microbiome metasecretome protein sequences. Furthermore, the present invention relates to a method for preparing a protein of the human microbiome metasecretome as well as to the use of such proteins in medicine.
