IFNG and neoplasm: A study using an analogue of vitamin E, α-tocopheryl succinate (αTOS), which is an esterified form of αToc, showed that supplementation of αTOS with nonmatured DC reduced the size of the tumour in 3LL lung cancer-bearing C57BL/6 mice and increased the levels of IFN-γ, which again suggest the involvement of the Th1-mediated immune response [33].
