Active delivery of trefoil factors by genetically modified Lactococcus lactis prevents and heals acute colitis in mice

Open access

Abstract

Background & aims Effective therapeutics for treating acute colitis, caused by disruption of the intestinal epithelial barrier, are scarce. Trefoil factors (TFF) are cytoprotective and promote epithelial wound healing and reconstitution of the gastrointestinal tract, which makes them good candidate therapeutics for acute colitis. However, orally administered TFF stick to the mucus of the small intestine and are absorbed at the cecum.Methods We have engineered the food-grade bacterium Lactococcus lactis to secrete bioactive murine TFF. The protective and therapeutic potentials of these TFF-secreting L. lactis were evaluated in parallel with purified TFF in the dextran sodium sulfate (DSS)-induced murine model for acute colitis and in established chronic colitis in interleukin (IL)-10(-/-) mice. Disease was evaluated by blinded macroscopic and microscopic inflammatory scores and by myeloperoxidase activity.Results Intragastric administration of TFF-secreting L. lactis led to active delivery of TFF at the mucosa of the colon and, in contrast to administration of purified TFF, proved to be very effective in prevention and healing of acute DSS-induced colitis. The in situ secreted murine TFF significantly decreased morbidity and mortality and stimulated prostaglandin-endoperoxide synthase 2 expression, which represents a major therapeutic pathway. In addition, this approach was successful in improving established chronic colitis in IL-10(-/-) mice.Conclusions We have positively evaluated a new therapeutic approach for acute and chronic colitis that involves in situ secretion of murine TFF by orally administered L. lactis. This novel approach may lead to effective management of acute and chronic colitis and epithelial damage in humans.

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.
