High-level expression of tetanus toxin fragment C in Escherichia coli
Fragment C is the C-terminal domain of the heavy chain of tetanus toxin that can promote the immune response against the lethal dose of this toxin. Therefore, this portion can be considered as a candidate vaccine against tetanus infection, which occurs by Clostridium tetani. The present study aimed to compare the expression of tetanus toxin fragment C in Escherichia coli BL21 (DE3) pLysS cells...
متن کاملCloning and expression of tetanus toxin C fragment (Fc) in prokaryotic vector for constructing recombinant protein based vaccine for tetanus
Tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. Fragment C (52 kD) of this toxin is responsible for binding to the neuronal membrane. For this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. Presently, w...
متن کاملCell surface-exposed tetanus toxin fragment C produced by recombinant Bacillus anthracis protects against tetanus toxin.
Bacillus anthracis, the causal agent of anthrax, synthesizes two surface layer (S-layer) proteins, EA1 and Sap, which account for 5 to 10% of total protein and are expressed in vivo. A recombinant B. anthracis strain was constructed by integrating into the chromosome a translational fusion harboring the DNA fragments encoding the cell wall-targeting domain of the S-layer protein EA1 and tetanus...
متن کاملFragment C of Tetanus Toxin: New Insights into Its Neuronal Signaling Pathway
When Clostridium tetani was discovered and identified as a Gram-positive anaerobic bacterium of the genus Clostridium, the possibility of turning its toxin into a valuable biological carrier to ameliorate neurodegenerative processes was inconceivable. However, the non-toxic carboxy-terminal fragment of the tetanus toxin heavy chain (fragment C) can be retrogradely transported to the central ner...
متن کاملExpression of tetanus toxin Fragment C in tobacco chloroplasts.
Fragment C (TetC) is a non-toxic 47 kDa polypeptide fragment of tetanus toxin that can be used as a subunit vaccine against tetanus. Expression of TetC in Escherichia coli and yeast was dependent on the availability of synthetic genes that were required to improve translation efficiency and stabilize the mRNA. To explore the feasibility of producing TetC in tobacco leaves, we attempted expressi...
