  • Publication number: 20220333072
    Abstract: The invention relates to a new process for manufacturing in vitro antigen-specific T lymphocytes (CellTrAg), marked with intracellular dye and expanded in the presence of monocytes loaded with the antigen and subsequently sorted based on the low intensity of intracellular dye where the low intensity of fluorescence is a marker of antigen-specificity in that a loss of fluorescence correlated with the intensity of proliferation. The antigen specificity is assessed in functional tests in which antigen-specific lymphocytes sorted on the basis of low fluorescence are more active than non-specific lymphocytes with high fluorescence during sort; activity is defined in the case of regulatory T lymphocytes as inhibition of effector lymphocyte function and in the case of T effector lymphocytes as enhancing the characteristics of these cells such as proliferation, production of cytokines and cytotoxic factors.

  • Patent number: 11072779
    Abstract: The invention relates to a new method for in vitro expansion of CD4+CD25HighCD127?/LOWfoxP3+Tregs, wherein the process of Treg expansion takes place permanently or temporarily at a temperature below 37° C., optimally at a temperature of 33° C., the isolated Tregs are expanded in SCGM or X-vivo-20 medium supplemented with human serum or with foetal bovine serum, and magnetic beads coated with anti-CD3 and anti-CD28 antibodies at 1:1 (cell:bead) ratio and interleukin-2 are added to the culture.
