    Journal: Vaccine; 2003 Jul 04; 21(23):3290-300. PubMed ID: 12804860.
    Abstract:
    Six peptides, A, B1, B, C, D and E derived from the primary sequence of Schistosoma mansoni glyceraldehyde 3-phosphate dehydrogenase (SG3PDH) were selected based on lowest homology to human G3PDH and used for immunization of BALB/c mice. Peptides B1 and D induced immunoglobulin (Ig) G1, IgG2a and IgG2b antibodies that reacted with native and denatured SG3PDH, and were associated with significant (P<0.05) increase in fecundity and burden of challenge worms, respectively. Peptides A, B, C and E elicited a modest cellular immune response, IgG2a and/or IgG2b antibodies, and no effect on challenge worm burden. In contrast, tetrameric multiple antigen peptide (MAP) constructs A, B, C or E elicited strong cellular immune responses and production of IgG1 and/or IgG2a and IgG2b antibodies against the homologous MAP and peptide and SG3PDH. The immune responses were associated with significant (P<0.05) decrease in challenge worm burden for MAP B, and significant (P<0.05) reduction in egg count per worm couple for MAP C or E. The data together indicated the nature and effect of immune responses vary for each SG3PDH-derived peptide.
