Turning on our immune sentries
Melbourne, Monash, UQ and the synchrotron find what sends our MAITs into action to protect our gut from invaders.
Our guts, lungs and mouths are lined with mysterious immune cells that make up to ten per cent of the T cells in our immune system. Last year Australian researchers showed that these cells act as sentinels against invading bacteria and fungi. Now they’ve identified the precise biochemical key that wakes up these sentries and sends them into action.
