In this study, design of PCR programmes with suitable parameters and optimization resulted in simpler and faster single-round amplification assays.

Not Open Access | The evolution and putative function of phosducin-like proteins in the malaria parasite Plasmodium

Using the uncharacterized phosducin-like protein from Plasmodium berghei PhLP-1, we investigated the evolution of PhLP proteins across all branches of the tree of life. As a result of our analysis, we have discovered the presence of two additional PhLP proteins in Plasmodium, PhLP-2 and PhLP-3. Sequence homology with annotated PhLP proteins in other species confirms that the Plasmodium PhLP-2 and PhLP-3 belong to the PhLP family of proteins.

Herein, we review the genetic alterations associated with erythrocytes or mediators of the immune system, which might influence malaria outcome.

Not Open Access | A Plasmodium multi-domain protein possesses multiple inositol phosphate kinase activities

To further investigate the InsPx metabolism in these parasites a Plasmodium protein possessing inositol phosphate kinase (IPK) activity was recombinantly expressed, purified and enzymatically characterized for the first time

Why are male malaria parasites in such a rush? Sex-specific evolution and host–parasite interactions

We reveal a novel form of host–parasite coevolution that enables parasites to evade host immune responses that negatively impact upon fertility.

NOT Open Access | Lipocalin 2 Bolsters Innate and Adaptive Immune Responses to Blood-Stage Malaria Infection by Reinforcing Host Iron Metabolism

Plasmodium parasites multiply within host erythrocytes, which contain high levels of iron, and parasite egress from these cells results in iron release and host anemia.
