Production of the 42-kDa fragment of Plasmodium falciparum merozoite surface protein 1, a leading malaria vaccine antigen, in Arabidopsis thaliana seeds

Immunogenicity of Self-Associated Aggregates and Chemically Cross-Linked Conjugates of the 42 kDa Plasmodium falciparum Merozoite Surface Protein-1

Self-associated protein aggregates or cross-linked protein conjugates are, in general, more immunogenic than oligomeric or monomeric forms. In particular, the immunogenicity in mice of a recombinant malaria transmission blocking vaccine candidate, the ookinete specific Plasmodium falciparum 25 kDa protein (Pfs25), was increased more than 1000-fold when evaluated as a chemical cross-linked prote...

Genetic Diversity Block 2 of Surface Protein-1 in Plasmodium Falciparum Merozoite by Nested-PCR Method in Southeastern Iran

Abstract       Background and Objectives: Plasmodium falciparum merozoite surface protein-1 (PfMSP-1) is a promising vaccine against malaria during its blood stages which play an important role in immunity to this disease. Polymorphic nature of this gene is a major obstacle in making an effective vaccine against malaria. In this study, the genetic diversity of Plasmodi...

Plasmodium falciparum merozoite surface protein 6 is a dimorphic antigen.

Merozoite surface protein 1 (MSP1) is a highly polymorphic Plasmodium falciparum merozoite surface protein implicated in the invasion of human erythrocytes during the asexual cycle. It forms a complex with MSP6 and MSP7 on the merozoite surface, and this complex is released from the parasite around the time of erythrocyte invasion. MSP1 and many other merozoite surface proteins contain dimorphi...

Protein-1 in Vaccinated Volunteers Merozoite Surface Plasmodium falciparum Responses to the 42-kDa Fragment of Ex Vivo Cytokine and Memory T Cell

Analysis of antibodies directed against merozoite surface protein 1 of the human malaria parasite Plasmodium falciparum.

The 190-kDa merozoite surface protein 1 (MSP-1) of Plasmodium falciparum, an essential component in the parasite's life cycle, is a primary candidate for a malaria vaccine. Rabbit antibodies elicited by the heterologously produced MSP-1 processing products p83, p30, p38, and p42, derived from strain 3D7, were analyzed for the potential to inhibit in vitro erythrocyte invasion by the parasite an...
