This Podcast features an interview with Elena M. Borroni and Raffaella Bonecchi, authors of a Research Article that appears in the 30 April 2013 issue of Science Signaling. Chemokines recruit leukocytes to sites of infection and inflammation by binding to chemokine receptors, which are members of the G protein-coupled receptor superfamily, present on the surface of leukocytes. Whereas activation of typical chemokine receptors leads to G protein-dependent signaling that promotes cell migration toward the chemokine source, activation of atypical chemokine receptors does not promote cell migration. Instead, signaling initiated by atypical chemokine receptors contributes to the immune response in other ways. The atypical chemokine receptor D6 is a scavenger that alters the chemokine gradient by binding to and degrading chemokines. Borroni and Bonecchi found that activation of a β-arrestin-dependent signaling pathway was necessary for D6 to act as a chemokine scavenger.
