This RNA Twist Could Rewrite What We Know About “Self” and “Nonself”

Scientists found that pseudouridine helps small RNAs pass on traits and avoid immune detection, offering clues for future RNA-based treatments and how the body tells “self” from “nonself.” Not everything inside us is, strictly speaking, part of us. The closer we examine the genome, the more we come to appreciate the role of small RNAs [...]
