WebApr 8, 2009 · The major symptom of cholera is massive watery diarrhea that occurs because of a toxin secreted by the bacteria that stimulates the cells of the small intestine to … WebMay 1, 2001 · Cholera toxin (CT) produced by Vibrio cholerae is the virulence factor responsible for the massive secretory diarrhea seen in Asiatic cholera. To cause disease, CT enters the intestinal epithelial cell as a stably folded protein by co-opting a lipid-based membrane receptor, ganglioside G M1.

Cholera toxin has been shown to enter cells via endocytosis in multiple pathways. These pathways include caveolae, clathrin-coated pits, clathrin-independent carriers (CLICs), and GPI -Enriched Endocytic Compartments ( GEECs) pathway, ARF6 -mediated endocytosis and Fast Endophilin-Mediated Endocytosis … See more Cholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is an AB5 multimeric protein complex secreted by the bacterium Vibrio cholerae. CTX is responsible for the massive, watery diarrhea … See more The complete toxin is a hexamer made up of a single copy of the A subunit (part A, enzymatic, P01555), and five copies of the B subunit (part B, … See more The gene encoding the cholera toxin was introduced into V. cholerae by horizontal gene transfer.

The polypeptide B binds to surface gangliosides on target cells. If the gangliosides were removed Select one: polypeptide A would enter the cells. vibrio cholera would not produce cholera toxin. polypeptide A would not be able to enter the cells. polypeptide A would bind to target cells. WebCholeragen initially interacts with cells through binding of the B subunit of the toxin to the ganglioside GM1 on the cell surface. Subsequent events are less clear. Patching or capping of toxin on the cell surface may be … Choleragen exerts its effect on cells through activation of adenylate cyclase. cryptographically random
