Topics Covered

• Chemokines are immune modulators regulating direction of cell migration
• Chemokine receptors are seven transmembrane (7TM) G protein-coupled receptors
• Chemokines need to bind to endothelial expressed proteoglycans for activity in vivo
• Excessive cell recruitment is a hallmark of inflammation
• 7TM receptors are highly druggable targets for the pharmaceutical industry
• Chemokine receptors are an essential co-receptor for HIV infectivity
• Nature uses chemokine binding proteins to iinhibit the chemokine system
