| Abstract: | Chagas' disease is a chronic disease affecting millions of people in Latin America. The cell surface of Trypanosoma cruzi, the etiological agent, is covered by a glycocalyx whose components play important roles in parasite survival and infectivity. The most abundant surface component is a glycolipid (glycoinositol phospholipid, GIPL) related in structure to glycosylphosphatidyl inositol anchors. In this review, we describe the biological effects of highly purified native GIPLs and their glycan or lipid moities on cells of the host immune system. |
