Parasite mitochondrial function (null)

"Parasite mitochondrial function" encompasses the metabolic and bioenergetic processes carried out by mitochondria in protozoan and helminthic parasites. The parasite mitochondrion is critical for ATP production, redox homeostasis, fatty acid and pyrimidine synthesis, and regulation of cell death. Notably, parasitic mitochondria often display unique biochemical properties, such as divergent electron transport chains or specialized enzymes (e.g., alternative oxidases), that differ significantly from those in their hosts. These differences have made various aspects of parasite mitochondrial function attractive targets for antiparasitic drugs. Several approved and experimental drugs, including atovaquone, ascofuranone, and nafuredin, target parasite mitochondrial electron transport, causing energetic collapse and parasite death. Due to the essentiality of mitochondrial function throughout the parasite life cycle, targeting these pathways offers broad potential for drug development, but selectivity and emergence of resistance present therapeutic challenges.
