Induction of sterilizing immunity by vaccination is extremely difficult because of the evasion mechanisms developed by parasites, and identification of new targets for therapy is therefore important. Glycosylphosphatidylinositols (GPIs) of parasites are glycolipids that participate in pathogenicity of parasitic diseases. Studies of Plasmodium falciparum and Trypanosoma brucei indicate that GPIs are good candidates for developing vaccines against malaria and sleeping sickness, respectively. By contrast, fatty acids isolated from P. falciparum and Toxoplasma gondii can inhibit the production of inflammatory cytokines induced by the GPIs in macrophages. GPIs are considered to be toxins that, if present in large amounts, induce irreversible damages to the host, and treatment with fatty acids could reduce this effect. Copyright © 2010 Elsevier Ltd.
