It is a critical stage in the parasite life cycle and, therefore, a logical step in which to intervene to prevent or ameliorate disease. Rodent models of malaria, commonly Plasmodium yoelii, are frequently used for studies of malaria pathogenesis. Little is known, however, about the invasion machinery of rodent malaria parasites. We have found previously that mice congenic for a region of chromosome 1, containing the Duffy antigen\/receptor for chemokines (DARC), have different susceptibility to P yoelii infection. Because P vivax, a human parasite, and P knowlesi, a simian parasite, use DARC to enter human erythrocytes, we sought to identify the role of the murine DARC in P yoelii invasion. Using a novel in vivo invasion assay and DARC knock-out mice, we found that DARC knock-out normocytes (mature erythrocytes) had negligible levels of P yoelii invasion compared with wild-type normocytes, demonstrating that DARC is a receptor for invasion of murine erythrocytes. In contrast, DARC knock-out reticulocytes were invaded at a rate similar to that for wild-type reticulocytes. We conclude that there is a DARC- independent pathway for reticulocyte invasion. These findings represent the first identification of a murine malaria receptor on erythrocytes and the first determination that different pathways of invasion exist on normocytes and reticulocytes. Because we show conservation of host\u2013receptor interactions between rodent and human malaria, we can now use this model to identify how immunity can interfere with the invasion process.<\/jats:p>","DOI":"10.1182\/blood.v99.8.2677","type":"journal-article","created":{"date-parts":[[2002,10,11]],"date-time":"2002-10-11T18:33:52Z","timestamp":1034361232000},"page":"2677-2684","update-policy":"https:\/\/doi.org\/10.1182\/blood.2019cm0000","source":"Crossref","is-referenced-by-count":32,"title":["Plasmodium
