Abstract

The incidence of inflammatory bowel disease is increasing all over the world, especially in industrialized countries. The aim of the present work was to verify the anti‐inflammatory activity of metabolites. In particular, cell‐free supernatants of Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, Lactobacillus reuteri, and Saccharomyces boulardii have been investigated. Metabolites produced by these probiotics were able to downregulate the expression of PGE‐2 and IL‐8 in human colon epithelial HT‐29 cells. Moreover, probiotic supernatants can differently modulate IL‐1 β, IL‐6, TNF‐α, and IL‐10 production by human macrophages, suggesting a peculiar anti‐inflammatory activity. Furthermore, supernatants showed a significant dose‐dependent radical scavenging activity. This study suggests one of the mechanisms by which probiotics exert their anti‐inflammatory activity affecting directly the intestinal epithelial cells and the underlying macrophages. This study provides a further evidence to support the possible use of probiotic metabolites in preventing and downregulating intestinal inflammation as adjuvant in anti‐inflammatory therapy.

  • Lactobacilli are known for intrinsic antioxidant properties; by increasing endogenous antioxidant enzyme activity and modulating systemic oxidative stress, they protect against carcinogen-induced cellular damage.

    “Lactobacilli, which are often used in dietary supplements, are known for their intrinsic antioxidant properties. By increasing endogenous antioxidant enzyme activity and modulating systemic oxidative stress, these probiotic strains protect against carcinogen-induced cellular damage72.”

    From Probiotic potential of Lactobacillus acidophilus TMPC 41127 isolated from traditional cheese in inhibiting Salmonella Typhi biofilms and virulence genes (2026) · cites this paper as [72]

    The Discussion reports that some lactobacilli have antioxidant effects and that some probiotics have been reported to increase antioxidant enzyme activity or modulate circulatory oxidative stress, protecting cells from carcinogen-induced damage. It does not establish that lactobacilli generally—or the particular strains referred to in the citing sentence—protect cells through those mechanisms. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
