Beschreibung:
The circumsporozoite (CS) protein of Plasmodium falciparum is the focus of intense efforts to develop an antisporozoite malaria vaccine. Localization of sites for T-cell recognition on this molecule is critical for vaccine design. By using an algorithm designed to predict T-cell sites and a large panel of H-2 congenic mice, a major nonrepetitive T-cell site was located. When a synthetic peptide corresponding to this site was covalently linked to the major B-cell site on the molecule, an immunogen capable of eliciting a high-titer antibody response was formed. This peptide sequence could prime helper T cells for a secondary response to the intact CS protein. The new helper T-cell site is located outside the repetitive region of the CS protein and appears to be the immunodominant T site on the molecule. This approach should be useful in the rational design and construction of vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Good, M F -- Maloy, W L -- Lunde, M N -- Margalit, H -- Cornette, J L -- Smith, G L -- Moss, B -- Miller, L H -- Berzofsky, J A -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1059-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434994" target="_blank"〉PubMed〈/a〉
