METHOD OF GENERATING ANTIGEN-SPECIFIC CYTOTOXIC CELLS WITH ANTITUMOUR ACTIVITY IN BREAST CANCER Russian patent published in 2014 - IPC C12N5/783 C12N5/784 A61K48/00 A61P35/00 

FIELD: biotechnology.

SUBSTANCE: method comprises isolation of mononuclear cells (MNC) from peripheral blood of a patient, separation of cells to adherent and non-adherent fractions, addition of the adherent fraction to the MNC of growth factors, loading of the dendritic cell with antigens of tumour lysate in vitro, the stimulation of maturation of dendritic cells for the next day. At that, the obtained immature DCs are added to lysate-autologous tumour cells at a dose of 100 mcg/ml, and after 48 hours within the subsequent 24 hours the rf-tumour necrosis factor-alpha is applied at a dose of 25 ng/ml. Then, the co-culture is carried out of mature dendritic cells activated with lysate and the non-adherent fraction of MNC at a ratio of 1:10 in the presence of recombinant human interleukin-12 at a dose of 10 ng/ml and the recombinant human interleukin-18 at a dose of 100 ng/ml.

EFFECT: invention enables to improve the level of cytotoxic and interferon-producing activity of antigen-activated dendritic cells while reducing the duration of their culture.
