High dose (3 × 108 CFU/kg) of DCG spore treatment leads to increased IFNγ secreting T cells in tumour, and low dose (1 × 108 CFU/kg) of DCG spore treatment leads to both IL-9 secreting T cells infiltrating to the tumour site, while the numbers of splenic IL-10 secreting T cells are increased in the low dose DCG spore treated group. Here, IL9 is linked to neoplasm.
