CCL5 (RANTES) is a chemokine produced mainly by T cells, platelets, macrophages, endothelial, and epithelial cells and by the myocardial tissue of T. cruzi-infected mice61 CCL5 recruits T cells, dendritic cells, monocytes, NK cells, and other cell types62 to sites of inflammation and infection due to the cell surface expression of CCR1, CCR3, and/or CCR5. The gene discussed is CCR3; the disease is infection.
