STING in Innate Immunity and Cancer: What’s the Buzz About? STING (STimulator of INterferon Genes protein) acts as a sensor of cytosolic DNA. Bacteria/Virus or self-derived DNA in the cytosol activates the STING pathway and promotes the production of type I interferons (IFN-alpha and IFN-beta). STING also ... Read full blog post. |
