Bringing natural killer cells to the tumor battlefield

http://ift.tt/eA8V8J By studying melanoma, a highly malignant form of skin cancer, medical researchers have revealed a mechanism by which the immunosuppressive environment can be switched to an immunosupportive one. They found that if autophagy -- the intracellular recycling process -- is blocked in tumor cells, they produce cytokines that attract NK cells. The massive recruitment of NK cells allows killing cancer cells and lets the tumors shrink.
