Epitopes for human CD4<sup>+</sup> cells on diphtheria toxin: Structural features of sequence segments forming epitopes recognized by most subjects
1 Dec 1995
Abstract excerpt
The sequence regions of diphtheria toxin (DTX) recognized by CD4+ T cells of seven healthy humans of different major histocompatibility complex haplotypes were identified. Overlapping synthetic peptides, screening the DTX sequence, were used to test in proliferation assays unselected blood CD4+ cells, or DTX-specific CD4+ lines propagated by stimulation with DTX of blood mononuclear cells. Blood CD4+ cells and...
