CCL2 and infection: These chemokines are critical for the recruitmentof leukocytes to sites of infection with varying target cell specificities.CXCL1 and CCL20, for example, attract neutrophils,32−34 whereas CCL1and CCL2 attract monocytes and macrophages.35,36 Additionally, CCL20 and CXCL10 recruit lymphocytes.34,37 Unsurprisingly, many of these cytokines have been implicated inGBS-associated disease.
