For several such \u201cPfATP4-associated\u201d compounds, it has been noted that their addition to parasitized erythrocytes results in cell swelling. Here we show that six structurally diverse PfATP4-associated compounds, including the clinical candidate KAE609 (cipargamin), induce swelling of both isolated blood-stage parasites and intact parasitized erythrocytes. The swelling of isolated parasites is dependent on the presence of Na\n            <jats:sup>+<\/jats:sup>\n            in the external environment and may be attributed to the osmotic consequences of Na\n            <jats:sup>+<\/jats:sup>\n            uptake. The swelling of the parasitized erythrocyte results in an increase in its osmotic fragility. Countering cell swelling by increasing the osmolarity of the extracellular medium reduces the antiplasmodial efficacy of PfATP4-associated compounds, consistent with cell swelling playing a role in the antimalarial activity of this class of compounds.\n          <\/jats:p>","DOI":"10.1128\/aac.00087-18","type":"journal-article","created":{"date-parts":[[2018,3,19]],"date-time":"2018-03-19T09:56:41Z","timestamp":1521453401000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":51,"title":["Cell Swelling Induced by the Antimalarial KAE609 (Cipargamin) and Other PfATP4-Associated Antimalarials"],"prefix":"10.1128","volume":"62","author":[{"given":"Adelaide S.
