Finding. When the zoonotic malaria Plasmodium knowlesi is grown in human red cells instead of macaque cells, it sprints through rings and rewrites, among other things, its mitochondrial respiratory complexes. Pazicky, Preiser, Bozdech and colleagues build a high-resolution intraerythrocytic transcriptome and then add proteomics and thermal stability across the two host cells. After the hurried ring stage, trophozoite and schizont timing match Plasmodium falciparum. The human-cell proteome moves glutathione synthetase earlier, plus NADPH production, glutamine synthesis, ribosomal subunits, and mitochondrial respiratory complexes. The authors call that a non-genetic adaptation to the human red cell.
Why this paper matters
P. knowlesi is already a human malaria in Southeast Asia. A cycle-resolved transcriptome is the resource. The mitochondrial clause is real and modest: respiratory-complex expression is on the adaptation list, not the only story. File it as host-cell bioenergetic remodeling in a stripped parasite mitochondrion.
What they actually measured
RNA time course, protein, thermal stability, macaque versus human RBCs. No parasite OCR in the abstract.
How to read the score
Low 70s. Real mito-complex expression change inside a broader paper. Confidence is medium.
Caveats
Culture. One clause. Thermal stability is not function.
What to do with it
If you culture P. knowlesi in human blood, use this clock and watch respiratory-complex proteins. If you wanted a malaria mitochondrion-drug paper, this is only a parts list.
