When your email is interrupted or blocked, it creates havoc. Messages remain undelivered, stalling interactions between you and your friends, family, and colleagues at work. Likewise when communication fails between your body’s cells, disease can result. Scientists recently discovered a new group of molecules called extracellular RNA (exRNA) that appears to travel between cells to help them communicate. Now, NIH is encouraging researchers to explore the potential of these newly discovered messengers.
