    IL-12 immunotherapy of minimal residual disease in murine models of HPV16-associated tumours: induction of immune responses, cytokine production and kinetics of immune cell subsets

  • Original language description

    In this model, upregulation of cytokine production was detected, compared to the animals without tumours. But, no differences in Th1/Th2 polarization of the immune responses were observed. In the spleens of TC-1 (MHC class I+) but not of TC-1/A9 (MHC class I?) treated tumour-bearing animals, the cytotoxic CD8+ cells were found. In the spleens of TC-1/A9 but not of TC-1 tumour-treated animals, the NK activity measured as the lysis of NK-sensitive YAC-1 targets was detected. Downregulation of the CD4+ andCD8+ subpopulations were not restored after therapy. The percentage of CD25+/CD4+ T regulatory cells in lymph nodes remained unchanged. The chemotherapy led to upregulation of immunosuppressive immature myeloid Gr-1+/CD11b+ (IMC) cells in the spleens oftreated animals. The accumulation of IMC was significantly decreased after subsequent IL-12 immunotherapy. That elimination may be responsible for the improvement of antitumour responses after adjuvant IL-12 vaccination.

    Imunoterapie minimální zbytkové choroby interleukinem 12 na myším modelu nádorů asociovaných s virem HPV 16: Indukce imunitní odpovědi, produkce cytokinů a kinetika subpopulací imunních buněk

  • Czech description

    U léčených myší byla detekována zvýšená produkce cytokinů, ale nebyl nalezen rozdíl v Th1/Th2 polarizaci imunitní odpovědi. Ve slezinách myší nesoucích TC-1 (MHC I+), ale ne TC-1/A9 (MHC I?) nádory, byly nalezeny cytotoxické CD8+ buňky. Ve slezinách léčených myší nesoucích TC-1/A9 nádory, byly naopak nalezena NK aktivita detekovatelná jako lýza NK senzitivních YAC-1 buněk. Snížený počet CD4+ a CD8+ buněk přetrvával I po léčbě; zatím co procento CD25+/CD4+ T regulačních buněk se neměnilo. Chemoterapie vedla ke zvýšení počtu imunosupresivních nezralých myeloidních buněk Gr-1+/CD11b+ (IMC) ve slezinách léčených zvířat. Jejich akumulace by mohla být zodpověná za zvýšení imunitní odpověďi po adjuvantní léčbě pomocí IL-12.
