Optimized Method for Purification of Expressed Plasmodium Vivax Duffy Binding Protein-II (PvDBP-II): Implication for Vivax Malaria Vaccine Development
Background: The purity and correct folding of a recombinant protein is critical for any structural, biochemical and vaccine design studies. Plasmodium vivax Duffy binding protein-II is a leading vaccine candidate for vivax malaria. In the present study, the purification process of recombinant DBP-IX (a variant form of PvDBP-II) was optimized to achieve the highest yield and purity. Moreover, ...
متن کاملStructure of the Plasmodium falciparum circumsporozoite protein, a leading malaria vaccine candidate.
The Plasmodium falciparum circumsporozoite protein (CSP) is critical for sporozoite function and invasion of hepatocytes. Given its critical nature, a phase III human CSP malaria vaccine trial is ongoing. The CSP is composed of three regions as follows: an N terminus that binds heparin sulfate proteoglycans, a four amino acid repeat region (NANP), and a C terminus that contains a thrombospondin...
متن کاملRationale for Further Development of a Vaccine Based on the Circumsporozoite Protein of Plasmodium vivax
Background Plasmodium vivax and its mosquito vectors have several distinctive characteristics that allow the transmission of this parasite in both temperate and tropical climates [1,2]. None, however, are as unique as its ability to form hypnozoites—dormant forms that reactivate periodically to cause multiple bouts of clinical malaria—that may be responsible for up to 80% of clinical episodes [...
متن کاملGenotyping of Iranian Plasmodium vivax populations by using circumsporozoite protein gene (CSP) marker
Although circumsporozoite protein of Plasmodium vivax (Pvcsp) has been considered to be a potential vaccine candidate, there was no information about the sequence variation in CSP of Iranian P. vivax. In current study, the prevalence of two types of Pvcsp was determined by PCR-RPLP in 374 P. vivax infected patients. In north, with one exception, all parasites were VK210, however, in south both ...
متن کاملA chimeric protein-based malaria vaccine candidate induces robust T cell responses against Plasmodium vivax MSP119
The most widespread Plasmodium species, Plasmodium vivax, poses a significant public health threat. An effective vaccine is needed to reduce global malaria burden. Of the erythrocytic stage vaccine candidates, the 19 kDa fragment of the P. vivax Merozoite Surface Protein 1 (PvMSP119) is one of the most promising. Our group has previously defined several promiscuous T helper epitopes within the ...
