    摘要: The circumsporozoite (CS) protein of Plasmodium falciparum has been analyzed to develop a new anti-sporozoite malarial 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 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 is capable of priming helper T-cells for a secondary response to the intact CS protein. This site represents the first helper T-cell site described for the CS molecule outside of the repetitive region, and is a major immunodominant T-site on the molecule. The approach described herein is useful in the rational design and construction of more efficacious vaccines.

    摘要: Methods are provided herein to prevent a tumor recurrence in a subject, involving administering to the subject an agent that blocks the TGF-β signaling pathway. In one embodiment, the agent inhibits the immunosuppressive effects of TGF-β. Also provided is a method of enhancing an immune respond in a subject to inhibit recurrence of a tumor by administering an agent which blocks the TGF-β signaling pathway. A method of enhancing the activity of an immune cell to inhibit recurrence of a tumor by contacting a TGF-β receptor-expressing cell with an agent which blocks the TGF-β signaling pathway is also provided, as are methods of screening for an agent that inhibits or measurably reduces the recurrence of a tumor.
