Remarkable stability in patterns of blood-stage gene expression during episodes of non-lethal Plasmodium yoelii malaria.

ABSTRACT:

Background

Microarray studies using in vitro cultures of synchronized, blood-stage Plasmodium falciparum malaria parasites have revealed a 'just-in-time' cascade of gene expression with some indication that these transcriptional patterns remain stable even in the presence of external stressors. However, direct analysis of transcription in P. falciparum blood-stage parasites obtained from the blood of infected patients suggests that parasite gene expression may be modulated by factors present in the in vivo environment of the host. The aim of this study was to examine changes in gene expression of the rodent malaria parasite, Plasmodium yoelii 17X, while varying the in vivo setting of replication.

Methods

Using P. yoelii 17X parasites replicating in vivo, differential gene ex
