Researchers have innovated a therapeutic food that significantly enhances beneficial gut microbes.
In a groundbreaking study published in Science, researchers from Washington University School of Medicine examined how gut microbiota can improve growth in malnourished children in Bangladesh.
The study revealed that a specific enzyme known as fatty acid amide hydrolase (FAAH), isolated from Faecalibacterium prausnitzii, plays a crucial role in influencing immune function pathways by hydrolyzing and synthesizing biomolecules necessary for growth.
Background
Research into gut microbiomes indicates that these microbial communities are capable of producing and modifying host signaling molecules that affect diverse biological functions such as metabolism, immune response, and even brain activities. This interaction is particularly vital during the formative years of growth.
Research among children in Bangladesh has uncovered that undernutrition disrupts gut microbiome equilibrium, leading to an immature bacterial community associated with stunted growth. This research prompted the formulation of a specialized microbiota-directed complementary food called MDCF-2, specifically designed to bolster beneficial gut bacteria in malnourished children.
Clinical trials featuring MDCF-2 have demonstrated notable improvements in weight gain, gut health markers, and enhanced height in malnourished children. In these trials, children consuming the MDCF-2 diet exhibited increased abundance of F. prausnitzii, which houses the enzyme FAAH pivotal for regulating health and promoting growth.
About the Study
The present research delves deeper into the role of the FAAH enzyme from F. prausnitzii, aiming to uncover how the MDCF-2 diet enhances specific bacterial activity and stimulates the production of bioactive molecules beneficial for child growth.
Experimental methodologies included the assessment of enzymatic activities of FAAH derived from the F. prausnitzii strain Bg7063, focusing on its significance in degrading specific fatty acid compounds termed N-acylethanolamides.
Murine models were utilized to explore colonization experiments using a 13-member or a 14-member bacterial community, the latter incorporating the F. prausnitzii Bg7063 strain. Researchers quantified levels of two N-acylethanolamides, oleoylethanolamide (OEA) and palmitoylethanolamide (PEA), in mouse cecal contents using advanced mass spectrometry.
Bg7063 cultures were complemented with isotope-labeled PEA to trace its degradation and confirm utilization. Mammalian FAAH inhibitors were employed to determine whether they effectively inhibited bacterial FAAH activity.
Ion-exchange chromatography techniques were implemented to identify proteins involved in N-acylethanolamide degradation. Enzymatic assays with varied amine and fatty acid compounds assessed the substrate preferences of FAAH. The researchers also investigated structural distinctions between mammalian and bacterial FAAH.
In vivo assays in mice were conducted to examine the biological impacts of various fatty acid amides. The team also performed ribonucleic acid (RNA) sequencing across the liver and various intestinal sections to analyze gene expression impacts related to the dietary intervention.
Ultimately, fecal samples from malnourished Bangladeshi children who participated in MDCF-2 dietary interventions were scrutinized, confirming FAAH’s role in modulating N-acyl amide levels and its influence on growth regulation.
Results
The study established that the MDCF-2 dietary intervention alters the gut’s chemical composition by modulating the FAAH activity from F. prausnitzii, thus affecting N-acyl amide levels. It was noted that the FAAH enzyme demonstrates dual functionality, enabling it to both hydrolyze and synthesize various N-acyl amides.
Importantly, FAAH from F. prausnitzii shows a broader operational range compared to human FAAH, displaying reduced sensitivity to conventional inhibitors, suggesting its vital role in modulating gut signaling molecules.
Analyses indicated that FAAH from F. prausnitzii could modulate the levels of bioactive amides such as OEA, which affects fat metabolism and feelings of fullness via peroxisome proliferator-activated receptor pathways. Children on the MDCF-2 diet exhibited diminished OEA levels in fecal samples alongside improved growth metrics, reiterating the relationship between gut microbial activity and appetite regulation.
Fascinatingly, FAAH’s processing of neuroactive and immune-modulating molecules suggests its potential influence on immune responses and mood regulation.
Conclusions
Overall, the findings underscore the promising application of FAAH from F. prausnitzii in microbiome-based therapy and its capability for regulating gut metabolites impacting appetite, immune function, inflammation, and mood. This research represents a pivotal advancement in the pursuit of microbial interventions in public health nutrition.

Gut Bacteria: The Hidden Heroes in the Battle Against Childhood Malnutrition!
Let’s talk about gut bacteria, shall we? You might think they’re just squatters in your intestines, but these little critters are now being crowned as the unsung heroes of nutritional science! Researchers from the Washington University School of Medicine have been delving deep into the world of gut microbiota, and guess what? They’ve whipped up a therapeutic food so powerful, it could throw a party and invite all the beneficial gut microbes in town.
In their recent study published in Science, these brilliant minds have discovered that a charming enzyme known as the fatty acid amide hydrolase (FAAH), produced by the gut microbe Faecalibacterium prausnitzii, plays a starring role in improving immune function pathways, particularly in malnourished kiddos in Bangladesh. Now that’s one busy little enzyme!
The Background: Microbiomes and Malnutrition
You see, our gut microbiota are not just passive observers; they’re actively engaging in a complex dance of digestion, immunity, and even brain function! It’s like a reality show inside your stomach. When malnutrition hits, particularly in young children, it can disrupt this delicate balance and lead to a less-than-ideal gut environment. Basically, think of it like someone crashing the party with a bad playlist—nobody’s dancing anymore!
The researchers noticed that undernourished Bangladeshi children were sporting immature gut microbiomes that correlated with their stunted growth. This dreadful combo sparked the brainy folks at Washington University to concoct a special brew called MDCF-2, aimed at boosting those good gut bacteria like they were on a mission to win a group talent show.
How They Did It: Science to the Rescue
In their quest, the researchers studied how the FAAH enzyme from our star player F. prausnitzii – a good buddy of gut health – works its magic in helping children grow. They utilized an arsenal of fancy terms to figure out exactly what the enzyme does in the body, including hydrolyzing and synthesizing important biomolecules. I mean who knew the intestines could be such a hotbed of action, right?
Using murine models (that’s a fancy term for laboratory mice, folks), they conducted colonizing experiments and examined the interaction of various fatty acids with the FAAH enzyme. They even pressed some enzymes against the wall to see who would flinch first. Spoiler alert: The FAAH from F. prausnitzii proved itself to be a superstar!
Results: The Triumph of Gut Science
As the study unfolded, they found that the MDCF-2 diet didn’t just quietly enhance gut bacteria; it actively influenced the overall health of these malnourished children.
