Protozoa are a diverse group of unicellular eukaryotes. Evidence has accumulated that protozoan aquaporin water and solute channels (AQP) contribute to adaptation in changing environments. Intracellular protozoan parasites live a well-sheltered life.Plasmodiumspp. express a single AQP,Toxoplasma gondiitwo, whileTrypanosoma cruziandLeishamniaspp. encode up to five AQPs. Their AQPs are thought to import metabolic precursors and simultaneously to dispose of waste and to help parasites survive osmotic stress during transmission to and from the insect vector or during kidney passages.Trypanosoma bruceiis a protozoan parasite that swims freely in the human blood. Expression and intracellular localization of the threeT. bruceiAQPs depend on the stage of differentiation during the life cycle, suggesting distinct roles in energy generation, metabolism, and cell motility. Free-living amoebae are in direct contact with the environment, encountering severe and sudden changes in the availability of nutrition, and in the osmotic conditions due to rainfall or drought.Amoeba proteusexpresses a single AQP that is present in the contractile vacuole complex required for osmoregulation, whereasDictyostelium discoideumexpresses four AQPs, of which two are present in the single-celled amoeboidal stage and two more in the later multicellular stages preceding spore formation. The number and regulation of protozoan aquaporins may reflect environmental complexity. We highlight the gated AqpB fromD. discoideumas an example of how life in the wild is challenged by a complex AQP structure-function relationship.
