Cure8 research brief
The review proposes S100B as a molecular link connecting enteric glial activation, intestinal barrier dysfunction, and liver/brain inflammation. If confirmed, this could help explain symptom overlap between gut and liver/brain complications and point to new biomarker or therapeutic research directions.
Clinicians and researchers working on IBD, gut–liver interactions, and neurogastroenterology; adult patients interested in biologic mechanisms behind gut–brain symptoms.
This is a narrative review (abstract-level summary provided). It synthesizes preclinical and clinical evidence that S100B acts both as a homeostatic factor at low levels and as an inflammatory "alarmin" when chronically elevated, engaging receptors such as RAGE, TLR2/4, and inflammasome pathways (NLRP3).
The authors discuss S100B presence in enteric glia, brain astrocytes, and certain liver cells and link its kinetics to acute versus chronic disease states like cirrhosis, IBD, IBS-D, and hepatic encephalopathy.
The review frames S100B as a candidate biomarker and mechanistic bridge in the brain–gut–liver axis, but emphasizes that causal roles, tissue sources, and clinical utility remain to be validated.
The source is a review article (Frontiers in Immunology) summarized at the abstract level; it compiles existing preclinical and clinical studies but does not establish definitive clinical utility for S100B.

The paper identifies subtype-specific changes in enteric glial cells and mast cell activity in microscopic colitis and shows some treatment-associated reductions after budesonide; that helps explain disease biology and...
Many people with IBD have ongoing IBS-like symptoms despite little or no intestinal inflammation. This project targets brain–gut and autonomic mechanisms that might explain symptom persistence and tests a non-drug...
This study offers a noninflammatory explanation for why many people with Crohn’s continue to have symptoms despite controlled inflammation: sulfur-producing gut microbes and their hydrogen sulfide byproduct. That could...
