Abstract

Objective: Recent studies have demonstrated that a variety of chemokine receptors are expressed in mast cells. We investigated the changes in mRNA expression of CXCRs in murine IL-3-dependent bone marrow-derived mast cells (BMMCs) to clarify how the CXCR expression is regulated in mast cells. Methods: Expression of CXCR mRNA was measured by RNase protection assay. Functional expression of CXCRs was confirmed by monitoring intracellular Ca²⁺ mobilization. Results: CXCR4 mRNA expression was transiently induced in BMMCs in serum-dependent fashion and was completely suppressed upon IgE-mediated antigen stimulation. In contrast, CXCR5 mRNA expression was induced upon IgE-mediated antigen stimulation. Changes in the intracellular Ca²⁺ mobilization induced by CXCL12 strongly indicated the functional expression of CXCR4. The decrease in CXCR4 and the increase in CXCR5 mRNA expression was also observed in BMMCs stimulated with thapsigargin, a phorbol ester, and stem cell factor. Conclusion: The mRNA expression of CXCR4 is differentially regulated in BMMCs upon various stimuli including IgE-mediated antigen stimulation.
