Vibrio cholerae -synthesized tryptophan activates innate immune signaling in enteroendocrine cells via phosphorylation of the nuclear receptor ultraspiracle

|
By Xiang Ding, Paula I. Watnick
| Nature Verified
Abstract The Gram-negative rod Vibrio cholerae causes profuse diarrhea in humans and is found in close association with both terrestrial and aquatic arthropods in the environment. Here we show that tryptophan produced by V. cholerae in the arthropod intestine activates expression of the host colonization factor Peritrophin-15a (Peri-15a). V.

Genetics and Molecular Biology Audrey S. Vanhove, Bat-Erdene Jugder, Daniela Barraza, Paula I. Watnick DOI: 10.1128/AEM.00371-20 ABSTRACT While only a subset of Vibrio cholerae are human diarrheal pathogens, all are aquatic organisms. In this environment, they often persist in close association with arthropods. In the intestinal lumen of the model arthropod Drosophila melanogaster, methionine and methionine sulfoxide decrease susceptibility to V. cholerae infection.
