| 英文摘要 | Three synthetic vespulakinin analogues either with or without carbohydrate moieties and mastoparan B isolated from Vespa basalis venom were investigated for their immunogenic activity and solution conformation. Mice immunized wilh these wasp venom peptides. with the exception of (Galα)Thr ��. (Galα)Thr ��- vespulakinin 1. showed positive antibody responses. However, the response elicited by mastoparan B was much higher than those induced by vespulakinin analogues. The class of antibody induced by these peptides was identified as an lgG �� isotype with �R -light chain, suggesting stimulation of a T-celldependent immune response by these peptides. According to the circular dichroism spectra of these peptides. the structures of the vespulakinin analogues in solution were largely unordered, while mastoparan B exhibited a conformation rich in α -helices. The presence of carbohydrate moieties and the rather random structure in vespulakinins may interfere with T-cell recognition of the peptides. leading to lower immune responses. |
