Vibrio Cholerae Toxin B Subunit
The recombinant B subunit of cholera toxin (CTB) is an immunogenic component included in oral cholera vaccines (e.g., Dukoral) that stimulates specific antibodies against the toxin binding subunit, blocking cholera toxin interaction with intestinal GM1 ganglioside receptors. CTB also cross-reacts immunologically with heat-labile enterotoxin of enterotoxigenic E. coli (ETEC), providing partial protection against traveler's diarrhea. It serves as both a vaccine antigen and a mucosal adjuvant that enhances immune responses to co-administered antigens.
