Abstract:
:Chemoattractant-stimulated granule release from neutrophils, basophils and eosinophils is critical for the innate immune response against infectious bacteria. Interleukin 8 (IL-8) activation of the chemokine receptor CXCRI was found to stimulate rapid formation of beta-arrestin complexes with Hck or c-Fgr. Formation of beta-arrestin-Hck complexes led to Hck activation and trafficking of the complexes to granule-rich regions. Granulocytes expressing a dominant-negative beta-arrestin-mutant did not release granules or activate tyrosine kinases after IL-8 stimulation. Thus, beta-arrestins regulate chemokine-induced granule exocytosis, indicating a broader role for beta-arrestins in the regulation of cellular functions than was previously suspected.
