AI Article Synopsis
- Bioactive components from Porphyra tenera (PT) have potential health benefits, particularly in relation to inflammatory bowel disease (IBD), which has not been thoroughly researched.
- A study with DSS-treated mice showed that PT supplementation reduced colitis severity by improving disease activity, repairing colonic damage, and lowering abnormal inflammation.
- Additionally, PT helped restore healthy gut microbiota and the production of beneficial short-chain fatty acids (SCFAs) and bile acids (BAs), suggesting edible seaweeds like PT could help prevent inflammation-related disorders in humans.
Article Abstract
Bioactive components from Porphyra tenera (PT) have been reported to confer various health benefits. The role of PT in inflammatory bowel disease (IBD) has not been fully investigated. This study aimed to explore the anti-inflammatory properties of PT on dextran sodium sulfate (DSS)-treated mice. PT supplementation attenuated the severity of colitis in DSS-treated mice, evidenced by the reduction of disease activity index (DAI), restoration of colonic histological damage and suppression of abnormal inflammatory response. Sequencing analysis indicated that intake of PT alleviated DSS-induced gut microbiota dysbiosis, accompanied by reversing the generation of short-chain fatty acids (SCFAs) and bile acids (BAs). Overall, our findings demonstrated that supplementation of PT attenuated the severity of intestinal inflammation and ameliorated gut microbiota dysbiosis in a murine colitis model, which provided a rationale for further application of edible seaweeds for preventing inflammation-related disorders in humans.
