The 3-phosphoinositide-dependent protein kinase 1 is an essential upstream activator of protein kinase A in malaria parasites (Publications)
t protein kinase A (PKA) signalling is essential for the proliferation of Plasmodium falciparum malaria blood stage parasites. The mechanisms regulating the activity of the catalytic subunit PfPKAc, however [...] function has not been investigated in gametocytes, the sexual blood stage forms that are essential for malaria transmission. By studying a conditional PfPKAc knockdown (cKD) mutant, we confirm the essential role
<em>Plasmodium falciparum</em>: extensive polymorphism in merozoite surface antigen 2 alleles in an area with endemic malaria in Papua New Guinea (Publications)

Rapid identification of malaria vaccine candidates based on alpha-helical coiled coil protein motif (Publications)
To identify malaria antigens for vaccine development, we selected alpha-helical coiled coil domains of proteins predicted to be present in the parasite erythrocytic stage. The corresponding synthetic peptides [...] various prevalence. Peptide specific antibodies were obtained both by affinity-purification from malaria immune sera and by immunization of mice. These antibodies did not show significant cross reactions
<em>Plasmodium falciparum</em>: malaria morbidity is associated with specific merozoite surface antigen 2 genotypes (Publications)
vaccine against blood stage malaria. In order to test if a specific genotype of the highly polymorphic MSA2 is associated with disease, we conducted a case-control study in a malaria endemic area of Papua New [...] as likely to be found in symptomatic malaria cases than in asymptomatic controls. Mixed genotype infections were significantly less frequent in symptomatic malaria infections. One individual allele (WOS10) [...] to lack of immunity to it. This study provides evidence that MSA2 is...

The malaria vaccine Combination B comprises recombinant Plasmodium falciparum ring-infected erythrocyte surface antigen and 2 merozoite surface proteins (MSP1 and MSP2) formulated in oil-based adjuvant [...] demonstrate functional activity of Combination B against P. falciparum in individuals with previous malaria exposure. The specific effects on parasites with particular msp2 genotypes suggest that the MSP2
