But what about innate immunity? Now, a study led by Prof. LI Ming from the Institute of Microbiology of the Chinese Academy of Sciences (CAS) reveals that CRISPR-Cas plays a broader role. Rather than acting alone like a solitary sniper shooting at phages, it also serves as a central command center, directing a network of diverse innate immune systems.<\/p>\n<p>This work was published in <em>Nature<\/em> on July 22.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>All cellular life-from humans to bacteria-possesses two layers of immunity: innate and adaptive.
