Clostridium butyricum-mediated intestinal microbiota modulation

Clostridium butyricum is a spore-forming, butyrate-producing obligate anaerobic bacterium found in the human gut and environment. As a probiotic, it is not a classical molecular target such as a receptor or enzyme, but functions by colonizing the intestine, competing with pathobionts, and fermenting dietary fibers to produce butyrate and other short-chain fatty acids. Butyrate has numerous local effects, including supporting regulatory T cell (Treg) differentiation, enhancing intestinal barrier integrity, and suppressing inflammation, primarily via inhibition of histone deacetylases (HDACs) and promotion of TGF-β expression. C. butyricum supplementation can shape gut microbiota composition, improve metabolic profiles, and modulate immune responses, making it an attractive therapeutic adjunct in conditions such as IBD, colitis, metabolic diseases, and potentially as an enhancer of cancer immunotherapy efficacy. However, C. butyricum is not a conventional drug target but a live microbial therapeutic agent[1][3][6][7][10].\n\nNote:\n- This query does not represent a standard molecular target but rather a therapeutic concept involving a microbial species and its ecological/functional actions.\n- For structured databases, the correct form should refer to individual molecules or mechanisms (e.g., \"Butyrate receptor\" or \"Histone deacetylase\") rather than \"Intestinal microbiota modulation via C. butyricum\" as a target.\n- Consider splitting this into related mechanisms or specifying the relevant host pathways impacted (e.g., butyrate’s effect on HDACs or Treg induction).
