title: The mysterious ways of the chemokine CXCL5.
abstract: The chemokine receptor CXCR2 binds several chemokines, some of them with functions yet to be defined. In this issue of Immunity, Mei et al. (2010) generated CXCL5-deficient mice and described a prominent role of CXCL5 in the regulation of CXCR2-dependent neutrophil trafficking during pulmonary host defense.
