  • Type III bacterial strains for use in medicine
    Publication number: 20040147719
    Abstract: The present invention relates to a safe non-virulent Yersinia enterocolitica mutant strain for delivering heterologous proteins in target cells carrying mutations in at least one of the effector genes yopH, yopO, yopP, yopE, yopM, yopT genes and at least one additional mutation in the invasin genes chosen from yadA and/or inv. The present invention also relates to a safe non-virulent Yersinia enterocolitica mutant strain for delivering heterologous proteins in target cells according to claim 1 carrying mutations in all effector genes yopH, yopO, yopP, yopE, yopM, yopT genes and at least one additional mutation in the invasin genes chosen from yadA and/or inv.

  • Tumor antigens and CTL clones isolated by a novel procedure
    Patent number: 6531451
    Abstract: The present invention relates to isolation of cytotoxic T lymphocyte (CTL) clones. In particular, the present invention relates to isolated CTL clones that are specific for MAGE-1 and MAGE-4, respectively. The CTL clones of the present invention have been isolated by successive steps of stimulation and testing of lymphocytes with antigen presenting cells which present antigens derived from different expression systems, e.g., from recombinant Yersinia, recombinant Salmonella, or recombinant viruses. The present invention further relates to the MAGE-1 and MAGE-4 antigenic peptides as well as the peptide/HLA complexes which are recognized by the isolated CTL clones.
