Hypothesis
Can transfected CHO cell lines be used to select for specific cytoadherent phenotypes in Plasmodium falciparum?
Conclusion
Transfected CHO cell lines are of limited use for creating monophenotypic cytoadherent parasite lines, but var transcription analysis can be performed without genetic manipulation.
Supporting Evidence
- Cytoadherence of Plasmodium falciparum-infected red blood cells is mediated by var gene-encoded proteins.
- Transcription profiles differed significantly between RT-PCR and RT-qPCR methods.
- Selection of parasites on CHO cells revealed different patterns of var transcription.
Takeaway
Researchers studied how malaria parasites stick to cells and found that using certain cell lines to select these parasites doesn't always work as expected.
Methodology
Parasites were panned on transfected CHO-cell lines and var transcripts were analyzed using RT-PCR and quantitative PCR.
Potential Biases
Potential bias due to the unknown receptor on CHO-745 cells affecting the results.
Limitations
The presence of an unknown receptor on CHO-745 cells complicates the selection process.
