Boulder Biofrontiers Scientist Joins $8.3M Research Study of Malnutrition and the Gut

We're finding out that there's a lot more to malnutrition among infants and children than just not getting enough to eat, or enough high-quality food. Individuals may develop malnutrition as a result of what is or isn't growing in their gut, where food gets processed. It's a fascinating insight with significant implications for treating a deadly world problem. In addition to getting sufficient good food, malnutrition could be addressed with novel dietary and microbial therapeutics, effectively optimizing a person's ability to draw nutrients and calories from the food and drink they take in, as well as making sure the immune system is being supported rather than compromised in the process.

The Bill and Melinda Gates Foundation exists to fund scientific projects with the kind of potential to make real change on the world health front, and to that end they've recently awarded $8.3M to a research study led by a Washington University St Louis School of Medicine team, in partnership with investigators at the University of Colorado Boulder and the University of California Davis, with a small number of other participants globally. The study is known as the Breast Milk, Gut Microbiome and Immunity Project, or BMMI, and it's really the next stage of research for Dr. Jeffrey Gordon at WUSTL, who began studying the interaction between food (mostly milk), gut flora, and immunity in malnourished children with a $5.5M Gates award in 2009.

Knight says of the BMMI study:

“Our hope is that by understanding the differences in individual gut microbial communities in both healthy and malnourished individuals, together with influences in diet including compounds and microbes transferred in breast milk, we will be able to better understand and develop new treatments for malnutrition...Such treatments could include prebiotics, probiotics, antibiotics or nutrition which might help reverse severe malnutrition in different individuals.”


Knight goes on to say that the personalized culture collections will be used to colonize lab mice in different combinations to test which microbial strains are most important. This mouse phase of the research project will be carried out in conjunction with researchers at UC Davis (read an earlier blog on Davis' genomic mouse resources here).

The BioFrontiers Institute researchers began moving into their new labs in the Jennie Smoly Caruthers Biotechnology Building earlier this year. (Read more about the interdisciplinary bioscience program and the biotech complex in our past CU-Boulder blogs.) Dr. Knight is also a Howard Hughes Medical Institute Early Career Scientist.
