Rotavirus 2/6 viruslike particles administered intranasally with cholera toxin, Escherichia coli heat-labile toxin (LT), and LT-R192G induce protection from rotavirus challenge.
We have shown that rotavirus 2/6 viruslike particles composed of proteins VP2 and VP6 (2/6-VLPs) administered to mice intranasally with cholera toxin (CT) induced protection from rotavirus challenge, as measured by virus shedding. Since it is unclear if CT will be approved for human use, we evaluated the adjuvanticity of Escherichia coli heat-labile toxin (LT) and LT-R192G. Mice were inoculated...
متن کاملExpression of proteins Heat-Labile (Lt-1) and Heat-Stable (STa) Escherichia coli expression of proteins Heat-Labile (Lt-1) and Heat-Stable (STa) Escherichia coli
Introduction Escherichia coli has a direct relationship with the diarrheagenic diseases, which occur quite in developing countries due to poor sanitation system and public health. It mainly affects children, causing a rate of morbidity and mortality worrying. This bacterium has a versatility of strains expressing different mechanisms and virulence factors, thus the importance in studying the ta...
متن کاملHeat - labile Enterotoxin of Escherichia coli
Heat-labile enterotoxin (LT) was obtained in large quantities (several-gram amounts) and great purity from Escherichia coli C600 carrying the LT-coding multicopy plasmid EWD299. By growing this strain on a medium that allows high cell densities in the early stationary phase, we increased the net LT production per milliliter by a factor of 200, compared to natural porcine enterotoxigenic E. coli...
متن کاملEscherichia coli Heat - labile Enterotoxin NUCLEOTIDE SEQUENCE
We report the complete DNA sequence of the Escherichia coli elt A gene, which codes for the A subunit of the heat-labile enterotoxin, LT. The amino acid sequence of the LT A subunit has been deduced from the DNA sequence of elt A. The LT A subunit starts with methionine, ends with leucine, and comprises 264 amino acids. The computed molecular weight of LT A is 29,673. The A subunit of cho...
متن کاملHeat-Labile Enterotoxin: Beyond GM1 Binding
Enterotoxigenic Escherichia coli (ETEC) is a significant source of morbidity and mortality worldwide. One major virulence factor released by ETEC is the heat-labile enterotoxin LT, which is structurally and functionally similar to cholera toxin. LT consists of five B subunits carrying a single catalytically active A subunit. LTB binds the monosialoganglioside G(M1), the toxin's host receptor, b...
