falciparumsporozoites were metabolically labeled in Dulbecco's modied Eagle's medium (DMEM) without Cys/Met, 1% BSA and 400 Ci/mL L-[35S]-Cys/Met for 1 hour at 28C and then kept on ice or chased at 28C for 2 hours in DMEM with Cys/Met and 1% BSA in the presence of the indicated concentrations of mAb5D5, in the presence of the isotype control mAb3D11 (specific against theP. againstPlasmodiumshould include the CSP N-terminal region. Keywords:antibodies, CSP, malaria,P. falciparum, sporozoites, vaccine The circumsporozoite protein (CSP) is the major surface protein ofPlasmodiumsporozoites, forming a dense coat on the parasite's surface. This protein plays a critical role in the journey ofPlasmodiumparasites from the mosquito to the mammalian host and it is expressed in sporozoites of rodent, primate, and humanPlasmodiumspecies. The basic structure of the CSP consists of a central…
