The candidate malaria vaccine RTS,S/AS01(E) provides significant but partial protection from clinical malaria. On in vitro circumsporozoite protein (CSP) peptide stimulation and intra-cellular cytokine staining of whole blood taken from 407 5-17 month-old children in a phase IIb trial of RTS,S/AS01(E), we identified significantly increased frequencies of two CSP-specific CD4+ T cells phenotypes...
Various pre-erythrocyte malaria vaccines are currently in clinical development, and among these is the adenovirus serotype 35-based circumsporozoite (CS) vaccine produced on PER.C6 cells. Although the immunological correlate of protection against malaria remains to be established, the CS antibody titer is a good marker for evaluation of candidate vaccines. Here we describe the validation of an ...
Antibodies to Plasmodium circumsporozoite protein (CSP) inhibit sporozoite's cell traversal activity
Antibodies against a synthetic peptide representing the repetitive epitope of the circumsporozoite protein (CS) of Plasmodium knowlesi have properties similar to those of antibodies against the native protein. Either antibody reacts with the synthetic peptide, cross-links the CS protein on the membrane of the parasite giving the CSP reaction, and neutralizes the infectivity of sporozoites. The ...
Immunoglobulin G (IgG) antibodies to three vaccine candidate preerythrocytic Plasmodium falciparum antigens were evaluated in children and adults in an epidemic-prone highland area of Kenya during rainy (high-transmission) and dry (low-transmission) seasons. The frequencies and median levels of IgG antibodies to circumsporozoite protein (CSP) and thrombospondin-related adhesive protein (TRAP) w...
