Scientists have found that a molecule produced by the body -- called LL-37 -- changes the way cells behave when they are invaded by bacteria.
The molecule acts like a fire alarm, experts say, warning the body's immune system of the infection and the need for urgent action.

The team, from the University of Edinburgh's Centre for Inflammation Research, focused on lung diseases caused by bacterial infections, which are a major cause of death worldwide.
These infections are increasingly resistant to antibiotics, making them difficult to treat.

Previous studies with mice found that LL-37 instructs cells in an infected lung to call in specialised cells, known as neutrophils, which can destroy bacterial threats.
In tests on human lung cells, researchers found that LL-37 specifically targets...
