STING pathway key to tumor immunity

A recently discovered protein complex known as STING plays a crucial role in detecting the presence of tumor cells and promoting an aggressive anti-tumor response by the body's innate immune system, according to two separate studies published in Immunity. The studies, both from University of Chicago-based research teams, have major implications for the growing field of cancer immunotherapy. The findings show that when activated, the STING pathway triggers a natural immune response against the tumor. This includes production of chemical signals that help the immune system identify tumor cells and generate specific killer T cells. The research also found that targeted high-dose radiation therapy dials up the activation of this pathway, which promotes immune-mediated tumor control. Read more here.
