Background Interleukin 1 receptor-like 1 (IL1RL1), also known as ST2, is a protein that in humans is encoded by the IL1RL1 gene. Two isoforms of ST2 were described in mammals: the membrane-bound ST2 (referred to as the ST2 receptor or ST2L), which provides the activation pathway, and the soluble ST2 (referred to as soluble ST2 or sST2) that originates from another promoter region of the il1rl1 gene and lacks the transmembrane and cytoplasmic domains. The ligand for ST2 is the cytokine Interleukin-33 (IL-33). There is clear correlation between T regulatory cell ST2 and Th2 specific transcription factor GATA3 expressions. Soluble ST2 is present in ST2+ T Regulatory cell. Releasing of sST2 into extracellular space cause neutralization of IL-33 and regulation of inflammation. ST2 Mutations have been linked to atopic dermatitis and asthma. The ST2 protein is also directly implicated in the progression of cardiac disease and is considered to be a cardiac biomarker. When the myocardium is stretched, the ST2 gene is upregulated, increasing the concentration of circulating sST2. The heart is subjected to greater stress in the presence of high levels of sST2. Binding of IL-33 to the ST2 receptor, in response to cardiac disease or injury, such as an ischemic event, elicits a cardioprotective effect resulting in preserved cardiac function.
