title: Use of human universally antigenic tetanus toxin T cell epitopes as carriers for human vaccination.
abstract: Synthetic constructs were assembled as multiple Ag peptide systems containing repetitive sequences of Plasmodium falciparum and Plasmodium berghei, the causative agents of human and murine malaria respectively, and two universal human tetanus toxin T cell epitopes 830-843 and 947-967. These constructs were tested for antibody production in mice and for their capacity to stimulate human PBL and tetanus toxin-specific T cell clones. A high antibody titer can be obtained in mice when multiple Ag peptide systems are injected in various adjuvants or in PBS alone. Furthermore, all constructs can activate PBL from every donor tested. However, a variable response was obtained when different clones specific for the two tetanus toxin universal epitopes were used. These constructs may represent possible candidates for a malaria vaccine.
