    摘要： The present invention provides an innovative versatile system, which allows delivery of one or several antigens or biologically active molecules into or onto targeted subset of cells. The invention is in particular directed to a combination of compounds and in particular to a composition, which comprises: (i) a fusion polypeptide comprising a streptavidin (SA) or avidin polypeptide and one or several effector molecule(s), wherein said fusion polypeptide retains the property of SA and avidin polypeptides to bind biotin; (ii) biotinylated targeting molecule(s), which are capable of targeting subset(s) of cells and/or cell surface molecule(s), and in particular dendritic cells (DC), subsets of DC and/or surface molecule(s) (including surface receptor(s)) of DC. The combination of the invention is suitable for use for targeting, in vivo, in vitro or ex vivo, of one or several effector molecule(s) to subset(s) of cells and/or cell surface molecule(s), and in particular for diagnosing or immunomonitoring a disease in a mammal or in prophylactic treatment and especially in vaccination and in therapy including in immunotherapy. The combination of the invention is also intended for use in vivo or ex vivo, for inducing a T cell immune response in bone marrow of naive donors before transplantation, or for activation and/or expansion of a T cell immune response in bone marrow of already immunized donors. The invention also relates to a method for the production of a fusion polypeptide of the invention and to a kit for a diagnostic test of a disease in a mammal, for immunomonitoring a disease in a mammal or for the prevention or treatment of a disease in a mammal.

    摘要： A genetically modified strain of M. tuberculosis or Mycobacterium bovis BCG is provided, wherein the genetically modified strain comprises at least one modified sequence comprising SEQ ID NO: 1, SEQ ID NO: 2, or both, having at least one mutation at T2, Q4, F8, A14, L28, L29, W43, G45, Y51, Q55, Q56, N66, M83, V90, M93, or F94 in SEQ ID NO:1; or at least one mutation at Q3, F7 A13, L27, W42, G44, Y50, Q54, N65, N67, M82, V89, M92, or F93 in SEQ ID NO:2, or a deletion at the terminal end of less than 20 amino acids. In a preferred embodiment, the mutation is at least one of T2H, Q4L, F8I, AI4R, L28A, L29S, W43R, G45T, Q55I, Q56A, N66I, N67A, M83I, V90R, M93T, or F94Q in SEQ ID NO:1, and Q3L, F7I, A13R, L27A, L28S, W42R, Q44T, Q54I, N65I, M82I, V89R, M92T, and F93Q in SEQ ID NO:2. Similarly, the genetically modified strain may also secrete ESAT-6 with a hexa-histidine tag, tetra-cysteine tag, or FLAG-tag, a GFP-fusion, or a short truncation at the C-terminal end of less than 20 amino acids.
