Aquaporin technology

Aquaporin technology is used to filter water by selectively moving water molecules through plasma membranes at a rapid speed. Aquaporins are transmembrane water channel proteins that work as nano-filters to block all other solutes from transporting through plasma membranes within living cells (Xie et al., 2013). Aquaporin membranes can be produced through the apical plasma membrane, which is the cell membrane on the surface of epithelial cells (Apical plasma membrane, 2021). This follows the action of vasopressin, which is responsible for activating protein kinase A (PKA), a holoenzyme, to phosphorylate aquaporin subunits contained in the cytoplasm (Litwack, 2020). Aquaporin channels are then formed as these subunits are inserted into the apical membrane (Litwack, 2020).

Aquaporine: Combattre la Crise Globale d'Eau en Utilisant le Filtre de la Nature

Une nouvelle technologie de traitement de l'eau utilisée par les astronautes à bord de la Station spatiale internationale pourrait fournir de l'eau propre à des millions de personnes dans le monde. En utilisant des protéines appelées aquaporines, ce système imite les capacités naturelles de filtration des reins humains et des racines des plantes pour purifier et recycler les eaux usées. Face à la demande mondiale croissante en eau, en particulier dans les régions reculées où l'eau potable n'est pas facilement accessible, cette technologie pourrait constituer une méthode de purification de l'eau plus économe en ressources, non seulement dans l'espace, mais aussi sur Terre.

Aquaporins: Fighting the global water crisis using nature’s own filter

A new water-treatment technology used by astronauts aboard the International Space Station has the potential to provide clean water to millions of people worldwide. By using proteins called aquaporins, this system mimics the natural filtering abilities of human kidneys and plant roots to purify and recycle wastewater. With an increasing global water demand especially in remote locations where clean drinking water is not easily accessible, this technology has the potential to provide a more resource-efficient method of water purification not only in space, but here on Earth as well.
