Anti-inflammatory activity of Chlorella polysaccharide AHP.
Article in Molecular and cellular biochemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Current medications for inflammatory bowel disease (IBD) are associated with various side effects. Researches had shown that bioactive substances (such as polysaccharides) exhibited anti-inflammatory activity, immunomodulatory activity and the property of the regulation of gut microbiota, which could contribute to the repair of colonic tissue and the improvement of intestinal health. The bioactive substances provided a new direction for developing safe, effective and novel therapeutic strategies. Therefore, the objective of this study was to evaluate the efficacy and safety of Chlorella polysaccharide AHP for the treatment of Caco-2 cell injury and ulcerative colitis in mice. This study investigated the anti-inflammatory activity of polysaccharide extracted from Chlorella (AHP) and its mechanisms through in vitro and in vivo experiments. In vitro, AHP significantly reduced reactive oxygen species (ROS) level, suppressed apoptosis and downregulated the levels of proinflammatory factors in dextran sulfate sodium (DSS)-induced Caco-2 cells, demonstrating antioxidant and anti-inflammatory effects. In vivo, AHP alleviated pathological damage of colon, decreased oxidative stress and levels of pro-inflammatory cytokines, enhanced expression of tight junction proteins and repaired intestinal mucosal barrier in mice with DSS-induced colitis. Furthermore, AHP modulated gut microbiota composition and levels of related metabolites, contributing to its anti-inflammatory activity through microecological regulation. These findings indicated that AHP mitigated DSS-induced cell injury and colonic damage via multiple pathways, confirming its potent anti-inflammatory properties through in vitro and in vivo experiments. This study provided important theoretical basis for exploring new treatments of IBD with bioactive substance AHP and developing functional foods based on AHP.
