  IL-2 and TRAIL are therapeutic agents known for their antitumor role, but they can be cleared quickly by the body or be cytotoxic, compromising their function. To reverse this impasse, the synthesis of these agents by live bacteria directly in the tumor is a viable approach, due to bacteria’s preference to colonize tumor tissue. It happens because of the high nutrient grid in this microenvironment and possible escape from the immune system since solid tumors are ischemic and have regions of hypoxia. In this context, attenuated Salmonella represents a promising live vector for delivery of antitumor molecules. The present study investigated the effects of IL-2, TRAIL and mixture of proteins expressed by recombinant Salmonella, strain SL3261, with unique and innovative construction with IL-2 and TRAIL proteins, on bladder cancer cells and in mice od C57BL/6.
