Chemotaxis, the movement of cells along chemical gradients, is critical for the recruitment of immune cells to sites of inflammation; however, how cells navigate in chemotactic gradients is poorly understood. Here, we show that macrophages navigate in a gradient of the chemoattractant C5a through the release of adenosine triphosphate (ATP) and autocrine "purinergic feedback loops" that involve receptors for ATP (P2Y(2)), adenosine diphosphate (ADP) (P2Y(12)), and adenosine (A2a, A2b, and A3… CONTINUE READING
