Glycolysis in the African Trypanosome : Targeting Enzymes and Their Subcellular Compartments for Therapeutic Development

Abstract EN

Subspecies of the African trypanosome, Trypanosoma brucei, which cause human African trypanosomiasis, are transmitted by the tsetse fly, with transmission-essential lifecycle stages occurring in both the insect vector and human host.

During infection of the human host, the parasite is limited to using glycolysis of host sugar for ATP production.

This dependence on glucose breakdown presents a series of targets for potential therapeutic development, many of which have been explored and validated as therapeutic targets experimentally.

These include enzymes directly involved in glucose metabolism (e.g., the trypanosome hexokinases), as well as cellular components required for development and maintenance of the essential subcellular compartments that house the major part of the pathway, the glycosomes.
