Congratulations to my first PhD student, Dr. Claire Chapman, on successfully defending her PhD!
Stay tuned for an exciting story about the role of the small intestinal microbiota in susceptibility to cholera! #ProudPI

My postdoc Dr. Maria de la Paz Gutierrez led this work showing that cholera toxin drives epithelial L-lactate production in the small intestine, creating a nutrient that Vibrio cholerae exploits during disease
Important and timely read in the New England Journal of Medicine:
Twelve former commissioners of the FDA express concern that the agency’s recent moves will undermine a regulatory model designed to ensure vaccine safety, effectiveness, and availability.
What do I love the most about UCSD? My amazing colleagues. Congratulations @chulab.bsky.social and @alistairrussell.bsky.social on your promotion and to Kees Murre for being elected to the NAS!

Gutierrez et al. show that cholera toxin induces epithelial LDHA-dependent L-lactate
production in the small intestine, creating a nutrient niche that Vibrio cholerae
exploits through LldD-mediated L-...

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
Twelve former commissioners of the FDA express concern that the agency’s recent moves will undermine a regulatory model designed to ensure vaccine safety, effectiveness, and availability.
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...
