Cholera toxin B subunit linked to glutamic acid decarboxylase suppresses dendritic cell maturation and function

Fusion of Cholera toxin B subunit (ctxB) with Shigella dysenteriae type I toxin B subunit (stxB), Cloning and Expression that in E. coli

Background and Objective: Shiga toxin (STx) is the main virulence factor in Shigella Dysenteriae type I and is composed of an enzymatic subunit STxA monomer and a receptor-binding STxB homopentamer. Shigella toxin B subunit (STxB) is a non-toxic homopentameric protein responsible for toxin binding and internalization into target cells by interacting with glycolipid (Gb3). Cholera toxi...

Cholera Toxin B-Subunit Prevents Activation

Novel immunostimulatory agent based on CpG oligodeoxynucleotide linked to the nontoxic B subunit of cholera toxin.

In this study, we report the development of a novel, rationally designed immunostimulatory adjuvant based on chemical conjugation of CpG oligodeoxynucleotide (ODN) to the nontoxic B subunit of cholera toxin (CTB). We demonstrate that the immunostimulatory effects of CpG can be dramatically enhanced by conjugation to CTB. Thus, CpG ODN linked to CTB (CTB-CpG) was shown to be a more potent stimul...

Nontoxic B Subunit of Cholera Toxin CpG Oligodeoxynucleotide Linked to the Novel Immunostimulatory Agent Based on

production of pentameric cholera toxin b subunit in escherichia coli

cholera toxin b subunit (ctb) has been extensively studied as an immunogen, adjuvant, and inducer of oral tolerance in many investigations. production of ctb has been carried out in the bacterial, plant, insect and yeast expression systems. in this study the expression of the ctb containing a 6xhis-tagged was performed by escherichia coli (e.coli) m15. the yield of purified pentameric recombina...
