  • Ex vivo generation of MHCII restricted CD4FOXP3regulatory T cells and therapeutic uses thereof
    Patent number: 11365392
    Abstract: The present invention relates to a method for ex vivo generating and expanding MHCII restricted CD4+ Foxp3+ regulatory T cells, and therapeutic uses thereof. The inventors here demonstrated the optimal conditions for inducing Foxp3 expression in naive CD3+ CD4+ TCR??+ MHCII restricted T following polyclonal or following antigen-specific activation. They also developed an experimental procedure to generate autologous CD8+ T cell lines functionally committed to lyse tumor-antigen specific FOXP3 expressing TCR??+ MHCII restricted T cells, pathogenic CD4+ T cells that favour tumor cell immune evasion. In particular, the present invention relates to a method for generating ex vivo MHCII restricted CD4+ Foxp3+ regulatory T cells having the following phenotype: CD3+ CD4+ Foxp3+.

  • Ex vivo generation of ?? Foxp3regulatory T cells and therapeutic uses thereof
    Patent number: 11198851
    Abstract: The present invention relates to a method for ex vivo generating and expanding ?? Foxp3+ regulatory T cells, and therapeutic uses thereof. The inventors performed the induction of Foxp3+ expression in ex vivo human induced tumor-antigen specific CD4+ TCR?? unrestricted T cells and the induction of autologous CD8-mediated T-cell responses against tumor-antigen specific FOXP3 expressing CD4+ TCR?? unrestricted T cells. The inventors developed a method to ex vivo generated and expanded antigen specific Foxp3 expressing CD3+ TCR??+ unrestricted T cells, committed to exclusively exert regulatory activity, whichever culture condition of stimulation is. In particular, the present invention relates to a method for generating ex vivo ?? Foxp3+ regulatory T cells having the following phenotype: CD3+ TCR??+ Foxp3+.
