Histopathological analysis of malaria-infected placentae has shown that maternal macrophages and fetal stromal cells contribute to CCL3, CCL4 and CXCL13 production in this organ (Abrams et al.2003; Muehlenbachs et al.2007), while CCL2, CCL3, CCL4 and CXCL10 have been found in intervillous blood monocular cells isolated from malaria-infected placentae (Suguitan et al.2003). Here, CCL4 is linked to malaria.
