Parasite lipids

Parasite lipids are essential structural and functional components of protozoan and helminthic organisms, playing pivotal roles in membrane architecture, signal transduction, and host-parasite interactions (Vial et al., 2003, doi:10.1016/S1473-3099(03)00722-3). These lipids often differ significantly from host lipids; for example, many protozoa utilize ergosterol or unique glycosylphosphatidylinositol (GPI) anchors that are absent or distinct in humans (Ferguson, 1999, doi:10.1126/science.285.5432.1368). These differences provide a therapeutic window for drugs like miltefosine, which interferes with phospholipid metabolism and cell signaling, and amphotericin B, which binds to parasite sterols to create lethal pores in the membrane (Dorlo et al., 2012, doi:10.1093/jac/dks210; Ellis, 2002, doi:10.1093/jac/dkf052). Targeting parasite lipid pathways is a proven strategy for treating diseases such as leishmaniasis, malaria, and Chagas disease. However, the complexity of lipid metabolism and the potential for host cell toxicity necessitate careful drug design to ensure selectivity and minimize adverse effects like hemolysis or organ damage.
