The circumsporozoite protein (CS) covers uniformly the plasma membrane of malaria sporozoites. In vitro, CS multimers bind specifically to regions of the hepatocyte plasma membrane that are exposed to circulating blood in the Disse space. The ligand is in the region II-plus of CS, an evolutionarily conserved stretch of the protein that has amino acid sequence homology to a cell adhesive motif o...

Despite declining the number of malaria cases in Iran, increased prevalence of malaria is supposed to be due to migration from eastern neighboring countries of Iran, which are abundant in Plasmodium vivax (P. vivax). The circumsporozoite protein (CSP) of the P. vivax, is one of the candidate antigens for antimalaria vaccine. The diversity of P. vivax populations circulating in Iran has been inv...

RTS,S is an advanced malaria vaccine candidate and confers significant protection against Plasmodium falciparum infection in humans. Little is known about the molecular mechanisms driving vaccine immunity. Here, we applied a systems biology approach to study immune responses in subjects receiving three consecutive immunizations with RTS,S (RRR), or in those receiving two immunizations of RTS,S/...

The relationship between anti- Plasmodium vivax circumsporozoite protein (CSP) antibody levels and the prevalence of malaria in epidemic areas of South Korea was evaluated. Blood samples were collected from inhabitants of Gimpo-si (city), Paju-si, and Yeoncheon-gun (county) in Gyeonggi-do (province), as well as Cheorwon-gun in Gangwon-do from November to December 2004. Microscopic examinations ...

Peptide vaccines containing minimal epitopes of protective Ags provide the advantages of low cost, safety, and stability while focusing host responses on relevant targets of protective immunity. However, the limited complexity of malaria peptide vaccines raises questions regarding their equivalence to immune responses elicited by the irradiated sporozoite vaccine, the "gold standard" for protec...

Entomological surveys were conducted in Mkuzi village in Muheza District, north-east Tanzania from April to September 2003. The objectives were to determine the species composition and infectivity rates of mosquitoes in Mkuzi village. Mosquito collection was done using CDC light trap and pyrethrum spray catch (PSC) techniques. The light trap: spray catch ratio was 2.2:1. A total of 2157 mosquit...
