My postdoc Paz asked how cholera toxin (CT) helps Vibrio cholerae thrive in the gut.
Turns out, CT rewires epithelial metabolism toward L-lactate production—fueling pathogen growth in the small intestine during disease

Cholera toxin (CT) promotes Vibrio cholerae colonization by altering gut metabolism to favor pathogen growth. We have previously found that CT-induced disease leads to increased concentrations of L-la...
