The emergence and spread of artemisinin resistance has compromised antimalarial efficacy. Here, Mok et al. apply quantitative transcriptomics, proteomics, and metabolomics to provide evidence that K13 mutations alter multiple aspects of the parasite

Imidazolopiperazines (IZPs) are a class of compounds under clinical development for malaria, but their mechanism of action is unclear. Here, the authors show that IZPs inhibit the parasite’s secretory pathway, affecting protein trafficking and expo

The emergence of mutant K13-mediated artemisinin (ART) resistance in Plasmodium falciparum malaria parasites has led to widespread treatment failures across Southeast Asia. In Africa, K13-propeller genotyping confirms the emergence of the R561H mutat
