Proposed model for STAT6-dependent IL-31RA expression in macrophages. IL-4/IL-13 bind with Type I and Type II IL-4 receptors and activate STAT6-mediated IL-31RA expression. Interaction of IL-31RA with IL-31 induces the expression of Fizz1 and SAA, which are involved in inflammation and tissue remodeling.
