Chemokines constitute a family of small heparin-binding proteins which orchestrate the infiltration of leukocytes during inflammation, but also directly influence other physiological and pathophysiological processes. In humans, more than 40 chemokines are known binding to around 18 G-protein-coupled receptors. A non-redundant role of certain chemokines and their receptors has been identified within the last years in inflammation and host defense. Among chemokine receptors, the CC chemokine receptors CCR1 and CCR2 have been shown to play a crucial role in these processes. Importantly, these receptors have already been targeted by specific antagonists in early human trials for autoimmune and infectious diseases. Although most of these antagonists failed to show any significant efficacy in the clinic, the knowledge of their biological effects could henceforth offer new avenues with optimal strategies for producing successful therapeutics.
