Every breath you take – how cell barriers protect the body

Some of the cells in our bodies communicate with each other to protect us from infection and a hostile environment – could they hold the secret to new ways to diagnose and treat disease?

Simon Jackson has been studying how cells of the immune system talk to barrier cells that protect our lungs. He is decoding the messages they send when faced with dangers, such as from infection or pollutants that we breathe in. Understanding the language of these cells will help develop new diagnostic and therapeutic strategies.
