Hypothesis
Can chloroquine regulate Plasmodium gene expression during its development in mosquitoes?
Conclusion
Chloroquine increases parasite load in mosquito salivary glands and interferes with the expression of at least two Plasmodium genes.
Supporting Evidence
- Chloroquine can modulate Plasmodium mosquito infection.
- Higher parasite loads were observed in salivary glands from mosquitoes that had a second blood meal containing chloroquine.
- Chloroquine increased the expression of Pyn_chl091 in mosquitoes.
Takeaway
Chloroquine, a malaria drug, can change how malaria genes work in mosquitoes, making them more infectious.
Methodology
Differential display RT-PCR was used to identify genes expressed during the sporogonic cycle that are regulated by exposure to chloroquine.
