New insight into immune cell behavior offers opportunities for cancer treatment

An international group of scientists has discovered that certain cells of our immune system—the so-called T cells—communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus of T cells. That insight offers new opportunities for the treatment […]
