Salt could help to boost the immune defense against cancer. This is suggested by research findings. Recently, adoptive T-cell therapy in particular has developed into an effective treatment tool. In adoptive T-cell therapy, the patient's own immune cells (T cells) are isolated from the blood and modified and multiplied in the laboratory in a therapy-specific manner. They are then reinfused into the patient and destroy tumor cells. The team has now discovered one of these factors: Sodium ions—a component of sodium chloride—increase the efficiency of antitumoral T cells. The researchers were able to show that breast cancer tumors have a...
