The recent discovery of the ST2 receptor ligand — interleukin-33 — has provided new insight into the importance of ST2 signalling as a mediator of inflammation. Now, an additional role for this pathway as a novel cardioprotective paracrine system is emerging. Here, Kakkar and Lee review these roles and discuss the therapeutic potential of targeting this pathway to treat associated diseases such as asthma, rheumatoid arthritis, atherosclerosis and heart failure.
