COPD is complex. A tangled mix of inflammatory pathways, immune cells and cytokines that all contribute to its debilitating symptoms.

​

While all attention has been on eosinophilic inflammation, due to new therapies that are able to address it, everyone seems to have forgotten one fundamental aspect of COPD - that it is primarily a neutrophilic disease.

​

We created an award-winning medical education programme that reminded HCPs that, to untangle the complexity of COPD, we need to follow the thread back to ST2/IL-33 - the pathway that can control both neutrophilic and eosinophilic inflammation.
