Abstract

IL-17 and TNF<b>α</b> synergistically induce surface expression of IL-13R<b>α</b>2 on primary lung fibroblasts, rendering them unresponsive to IL-13. Neutralizing antibodies to IL-13R<b>α</b>2 restored IL-13-mediated signaling and transcriptome studies confirmed IL-13R<b>α</b>2 is an IL-13 decoy receptor.
