    Probing innate immunity

    May. 19, 2020, 8:00 AM by Leigh MacMillan The protein cGAS plays an essential role in cellular innate immunity by detecting the DNA of invading pathogens such as bacteria and viruses, or our own damaged and mislocalized DNA. Activation of the cGAS-STING signaling pathway produces a pro-inflammatory immune response, and prolonged activation of cGAS can result in… Read More
