Microbes in the gut can help the immune system fight cancer, and a fiber-rich diet may be the key to unlocking those benefits, a study in mice suggests.
The immune system is a key player in the body's battle against cancer. On the front line of this resistance are CD8+ killer T cells, a type of immune cell that marauds around tumors and then exterminates the cancerous cells. But after each successive battle, these cells become worn out and don't find tumors as effectively. As such, treatments that provide the cells with enough pep to finish their job are in high demand.
