In a groundbreaking study published in Frontiers in Immunology, researchers from Tokyo University of Science have uncovered a potential mechanism by which gut bacteria can positively influence inflammatory bowel disease (IBD). This discovery has significant implications for the probiotic industry, including companies like Wecare Probiotics Co., Ltd., which is dedicated to the research and development of probiotic strains and their applications.

Key Findings of the Study

The study, led by Professor Chiharu Nishiyama, explored the anti-inflammatory effects of a gut bacteria-generated linoleic acid metabolite known as KetoC. The research highlighted how gut microbiome metabolites, particularly those derived from polyunsaturated fatty acids (PUFAs) like linoleic acid, can modulate immune responses and reduce inflammation in IBD.

In Vitro Insights:

The research focused on the effects of PUFA derivatives, specifically the metabolites of linoleic acid: KetoC, alpha-KetoC, and gamma-KetoC.

These enon derivatives markedly reduced levels of interleukin 2, a protein that triggers immune cell expansion and inflammation.

The original PUFAs did not show the same effects, underscoring the importance of bacterial conversion in activating their immunomodulatory properties.

Gamma-KetoC, in particular, was found to suppress prolonged T-cell proliferation and dendritic cell activation, both of which are linked to inflammation and autoimmune diseases.

The study also highlighted the involvement of G protein-coupled receptors (GPCR) and the transcription factor NFR2 in mediating these effects, with gamma-KetoC stimulating the NRF2 signaling pathway to suppress inflammatory cytokine production.

In Vivo Insights:

The in vitro findings were validated using a mouse model of IBD.

Gamma-KetoC treatment significantly reduced fibrosis-induced tissue damage in the colon, colitis-induced weight loss, and improved stool scores.

Treated mice showed decreased epithelial cell disruption, reduced infiltration of immune cells, and lower serum levels of inflammatory factors.

Mice deficient in NRF2 showed significant restoration following gamma-KetoC treatment, indicating the crucial role of this pathway in mediating the metabolite's anti-inflammatory effects.
