Potent in vivo anti-malaria activity of Goniothalamin against rodent malaria parasite infection in mice
Goniothalamin was evaluated for its anti-malaria activity in-vivo, using the 4-Day Suppressive Test (Peters & Robinson, 1975). The test were carried out against two strains of rodent malaria parasites, the sensitive strain P. berghei ANKA (MRA 311) strain and the resistant strain P. yoelii (MRA 312). An Initial screening was carried out using a single dose of 10 mg/kg body weight administered s...
متن کاملStructural and Immunological Characterization of Recombinant 6-Cysteine Domains of the Plasmodium falciparum Sexual Stage Protein Pfs230.
Development of a Plasmodium falciparum (Pf) transmission blocking vaccine (TBV) has the potential to significantly impact malaria control. Antibodies elicited against sexual stage proteins in the human bloodstream are taken up with the blood meal of the mosquitoes and inactivate parasite development in the mosquito. In a phase 1 trial, a leading TBV identified as Pfs25-EPA/Alhydrogel® appeared ...

متن کاملA Plant-Produced Pfs25 VLP Malaria Vaccine Candidate Induces Persistent Transmission Blocking Antibodies against Plasmodium falciparum in Immunized Mice
Malaria transmission blocking vaccines (TBVs) are considered an effective means to control and eventually eliminate malaria. The Pfs25 protein, expressed predominantly on the surface of the sexual and sporogonic stages of Plasmodium falciparum including gametes, zygotes and ookinetes, is one of the primary targets for TBV. It has been demonstrated that plants are an effective, highly scalable s...
متن کاملDisulfide bond mapping of Pfs25, a recombinant malaria transmission blocking vaccine candidate
A liquid chromatography tandem-mass spectrometry method was developed to map the eleven disulfide bonds in Pfs25, a malaria transmission-blocking vaccine candidate. The compact and complex nature of Pfs25 has led to difficulties in prior peptide mapping efforts. Here, we report confirmation of proper disulfide pairing of a recombinant Pfs25, by optimizing denaturation and digestion with trypsin...
