Cytotoxicity of diphtheria toxin A fragment to toxin-resistant murine cells delivered by pH-sensitive immunoliposomes.
pH-sensitive immunoliposomes composed of dioleoylphosphatidylethanolamine and oleic acid (8:2 molar ratio) mediated the delivery of the cytotoxic fragment A of diphtheria toxin to the cytoplasm of target L-929 cells. Free fragment A, fragment A encapsulated in antibody-free liposomes, or fragment A encapsulated in pH-insensitive immunoliposomes was not effective in the inhibition of the cellula...
متن کاملTowards a recombinant vaccine against diphtheria toxin.
Two recombinant fragments of diphtheria toxin (DT) were fused to an engineered tandem repeat of the immunoglobulin (Ig) binding domain of protein A, called ZZ. These fragments are (i) the receptor binding domain (DTR), which comprises amino acids 382 to 535 of DT, and (ii) a linear peptide (DT(168-220)) which comprises residues 168 to 220 of the loop between fragment A and fragment B of DT. The...

متن کاملExpression of diphtheria toxin fragment A and hormone-toxin fusion proteins in toxin-resistant yeast mutants.
Mutants of the eukaryote Saccharomyces cerevisiae, previously selected for resistance to diphtheria toxin, were investigated for their suitability as hosts for the expression of tox-related proteins. The structural gene for the toxin, encoding the fragment A catalytic domain, was modified for efficient intracellular expression in eukaryotes and placed downstream of the yeast GAL1 promoter eleme...
متن کاملInterleukin 2-diphtheria toxin fusion protein can abolish cell-mediated immunity in vivo.
De novo expression of the interleukin 2 receptor (IL-2R) is a critical and pivotal event in initiation of an immune response. Targeting the low-affinity IL-2-binding p55 subunit of the high-affinity IL-2R with the rat anti-mouse IgM monoclonal antibody M7/20 suppresses a variety of T-cell-mediated reactions, including transplant rejection, autoimmunity, and delayed-type hypersensitivity (DTH). ...
