pdf High intake of vegetables is linked to lower white blood cell profile and the effect is mediated by the gut microbiome. Current Opinion in Gastroenterology. Harvard University. By contrast, none of these 19 inflammatory proteins decreased in participants assigned to a high-fiber diet rich in legumes, seeds, whole grains, nuts, vegetables and fruits.
On average, the diversity of their gut microbes also remained stable. The study published online July 12 in Cell. Justin and Erica Sonnenburg and Christopher Gardner are co-senior authors. The lead authors are Hannah Wastyk , a PhD student in bioengineering, and former postdoctoral scholar Gabriela Fragiadakis, PhD, who is now an assistant professor of medicine at UC-San Francisco.
A wide body of evidence has demonstrated that diet shapes the gut microbiome, which can affect the immune system and overall health. According to Gardner, low microbiome diversity has been linked to obesity and diabetes.
The researchers focused on fiber and fermented foods due to previous reports of their potential health benefits. While high-fiber diets have been associated with lower rates of mortality, the consumption of fermented foods can help with weight maintenance and may decrease the risk of diabetes, cancer and cardiovascular disease.
The researchers analyzed blood and stool samples collected during a three-week pre-trial period, the 10 weeks of the diet, and a four-week period after the diet when the participants ate as they chose. The findings paint a nuanced picture of the influence of diet on gut microbes and immune status.
On one hand, those who increased their consumption of fermented foods showed similar effects on their microbiome diversity and inflammatory markers, consistent with prior research showing that short-term changes in diet can rapidly alter the gut microbiome. The results also showed that greater fiber intake led to more carbohydrates in stool samples, pointing to incomplete fiber degradation by gut microbes.
These findings are consistent with other research suggesting that the microbiome of people living in the industrialized world is depleted of fiber-degrading microbes.

The experiments Protein and heart health a microbial molecule, the Immmune-boosting and release Immune-boosting microbiome micrkbiome are influenced by host diet. Immune-bosoting Immune-boosting microbiome, in turn, stimulates the activation and signaling of a subset of cells known as natural killer NK T cells, which are involved in immune regulation and implicated in a range of inflammatory conditions. While scientists have surmised for a long time that diet plays a role in immune health, the new study elucidates the precise molecular cascade behind this interplay, said study senior author Dennis Kasperprofessor of immunology in the Blavatnik Institute at Harvard Medical School. If confirmed in larger animals and eventually in humans, the findings can help inform the design of small-molecule treatments that enhance both intestinal and overall immunity, the researchers said.Immune-boosting microbiome -

Introduction The human body, including the gut, skin and other mucosal environments, is colonized by a tremendous number of microorganisms, collectively termed the microbiome.
Interaction between microbiota and immune system in homeostasis Host-induced compartmentalization of intestinal microbiota The best-studied interface for host-microbiota interactions is the intestinal mucosa.

Diet-induced microbiome alterations Recent studies began to unravel the links between dietary microbiota modulation and host immunity. Crosstalk between microbiota and extra-intestinal organ immunity Although most studies in the field to date focused on the interplay of microbiota and mucosal immunity in the intestine, interactions of both the gut microbiota and extra-intestinal microbiota communities with extra-intestinal organ immunity have been gaining increased attention Fig.
Challenges and pitfalls in immune-microbiome research Recent research has greatly enhanced our understandings of the intimate but complicated crosstalk between the microbiome and the immune system. Perspectives A massive effort during the past decade in studying microbiome-immune interactions has led to better understanding of their molecular basis, while pointing to the importance of these interactions in impacting a variety of human immune-related diseases.

In the past several years, research on the microbiome has grown exponentially. Scientists have found that the microbiome is essential in shaping the development of innate and adaptive immunity and, in turn, the immune system shapes the microbiome.
Now, NCI-funded researchers are working to gain a better understanding of how the microbiome influences cancer development and the response to therapy. Recent findings show the promise of this emerging area of research:.
Metabolites produced by gut microbes appear to play an important role in antitumor immunity. When the investigators used antibiotics to selectively kill the bacteria, NKT cells accumulated in the liver and inhibited liver tumor growth.
Based on this laboratory research, a clinical trial initiated at the NIH Clinical Center is testing a combination of the antibiotic vancomycin, which kills Clostridium species, with other drugs that enhance antitumor immune responses. NCI-funded researchers have revealed associations between the gut microbiome and responses to cancer immunotherapy.
For example, investigators at MD Anderson and the University of Chicago have found that certain types of gut bacteria in patients with cancer are associated with clinical responses to immune checkpoint inhibitors.
Research is shedding light on how these microbes might exert their effects, including by influencing the function of dendritic cells and their ability to initiate an attack by the adaptive immune system. Researchers have also discovered that certain microbes are associated with the development of cancer.
For instance, the bacterium Fusobacterium nucleatum is strongly associated with colorectal cancer. NCI-funded research indicates that this bacterial species affects the activity of both innate and adaptive immune cells, leading to the development of an immunosuppressive tumor microenvironment and promoting colorectal cancer progression.
Scientists are using this knowledge to develop cancer prevention and treatment strategies aimed at disrupting the effects of this bacterium. NCI-funded research on innate immunity and the interactions between resident microbial species and the immune system is revealing many new opportunities for additional progress against cancer.
Achieving a better understanding of how bacteria interact with immune cells in patients with cancer will lead to entirely new therapeutic approaches, as well as improvements in existing treatments.
In the future, it may even be possible to develop "bugs as drugs," using genetically engineered microbes to promote potent antitumor immune responses.
