IL6 and neoplasm: At the same time, they are also capable of exhibiting anti-oncogenic effects: for example IL-1ß, IL-6, IL-8—by involving various links of the immune system in the antitumor response; TNF-α—being an apoptosis inducer; and IL-10—due to antagonism in relation to pro-inflammatory interleukins and increasing the production of toxic molecules in the tumor (for example, nitric oxide NO), which prevent the growth of the neoplasm [10].
