IL6 and asthma: Promote the formation of Treg cells, which is responsible for the production of IL‐10.Suppress TH2‐driven allergic responses in the mice model of ragweed‐induced asthma.Play an antifibrosis role by activating IL‐6/STAT3 signaling, thereby increasing the expression level of antifibrotic chemokine IFN‐γ‐inducible protein 10 (IP‐10, also called CXCL10).
