An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host. Exotoxins may be secreted, or, similar to endotoxins, may be released during lysis of the cell. Gram negative pathogens may secrete outer membrane vesicles containing lipopoly… WebCholera 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 …
