Abstract

FcεRI expression and function is a central aspect of allergic disease. Using bone marrow-derived mouse mast cell populations, we have previously shown that the Th2 cytokine IL-4 inhibits FcεRI expression and function. In the current study we show that the Th2 cytokine IL-10 has similar regulatory properties, and that it augments the inhibitory effects of IL-4. FcεRI down-regulation was functionally significant, as it diminished inflammatory cytokine production and IgE-mediated FcεRI up-regulation. IL-10 and IL-4 reduced FcεRI β protein expression without altering the α or γ subunits. The ability of IL-4 and IL-10 to alter FcεRI expression by targeting the β-chain, a critical receptor subunit known to modulate receptor expression and signaling, suggests the presence of a Th2 cytokine-mediated homeostatic network that could serve to both initiate and limit mast cell effector function.
