Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study led by King’s College London. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the study published in the journal Nature Medicine.
The team discovered that
whilst T cells in newborn babies are largely different to those in
adults, it is not because they are immunosuppressed; rather, they
manufacture a potent anti-bacterial molecule known as IL8 that has not
previously been considered a major product of T cells, and that
activates neutrophils to attack the body’s foreign invaders.
