Respiratory allergies: newly discovered molecule plays a major role in triggering inflammation

Caption

Microscopic visualisation of immune cells (in green) activated by the alarmins TL1A and interleukin-33 during the onset of allergic inflammation in the lungs. ILC2s immune cells produce large quantities of interleukin-9, a key mediator of allergic inflammation. They are located near collagen fibres (blue) and blood vessels in the lung (red).
