Together, our data provide fundamental insights into transcript-protein relationships in P. falciparum that are important for the correct interpretation of transcriptional data and that may facilitate the improvement and development of malaria diagnostics and drug therapy.

We describe here a novel method for polysome profiling in P. falciparum, a powerful approach which allows both a global view of translation and the measurement of ribosomal loading and density for specific mRNAs.

To examine the potential functional role of FV-associated Pfeno, we assessed the ability of Pfeno to complement a mutant Saccharomyces cervisiae strain deficient in enolase activity. In this strain (Tetr-Eno2), the enolase 1 gene is deleted and expression of the enolase 2 gene is under the control of a tetracycline repressible promoter.

Thus, our results show that active PM at delivery is associated with a marked suppression of P. falciparum-specific cellular neonatal immune responses, affecting secretion of both pro- and anti-inflammatory cytokines.
