Phospho-Proteomic Analysis of Interleukin-13 Signaling in Airway Cells Reveals SRC Family Kinase Involvement in Interleukin-13-Induced Inflammatory Responses.

ABSTRACT:

Introduction

Allergic asthma is a chronic inflammatory airway disease driven by the cytokine interleukin-13 (IL-13). Although IL-13 signals through the canonical JAK1/TYK2/STAT6 pathway, our understanding of the totality of IL-13-induced signaling intermediates is incomplete.

Methods

To address this, we performed a phospho-proteomic analysis of IL-13-stimulated A549 human airway epithelial cells. IL-13 stimulation led to differential phosphorylation at 145 unique serine/threonine residues across 92 proteins involved in diverse cellular processes. In silico analysis was used to predict kinases responsible for the observed changes, and therapeutics which may reduce IL-13-mediated pathology. The activation of these kinases and the ability of these therapeutics to limit IL-13 ac
