In the case of severe asthma… “Our orders came from the epithelium”
Much of the recent research into severe asthma has focused on the downstream mediators of airway inflammation. But perhaps it is time to examine the role of mediators at the top of the inflammatory cascade…
TSLP, IL-25 and IL-33, key epithelial cytokines, can be real masterminds behind inflammation, giving orders for downstream effector cells to follow [1, 2, 3].
Focusing on epithelial cytokines at the top of the inflammatory cascade offers a new way to think about severe asthma [1, 2, 3, 4].
Review the evidence to discover more about how epithelial cytokines can be real masterminds behind inflammation.
Epithelial cytokines such as TSLP, IL-23 and IL-33 can play a key role in allergic and eosinophilic inflammation [1, 2, 4, 5, 6, 7]. TSLP can also affect airway smooth muscle cells [4].
