Microbiota and lipid mediators: from molecular crosstalk to therapeutic opportunities.
Review in Frontiers in pharmacology, 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
The gut microbiota constitutes a metabolically active ecosystem that dynamically interacts with the host lipid metabolism and cellular signaling networks. While dietary lipids shape the microbial composition and metabolite production, the microbiota reciprocally biotransform fatty acids, thereby regulating lipid mediator bioavailability and host cellular responses. This bidirectional molecular crosstalk plays a pivotal role in maintaining metabolic homeostasis, epithelial barrier integrity, and immune regulation. Microbiota-derived lipid signals, including short-chain fatty acids, bile acids, polyunsaturated fatty acid-derived intermediates, sphingolipids, and N-acyl amides, modulate the balance between pro-inflammatory eicosanoids and specialized-pro resolving mediators. Through the engagement of G protein-coupled receptors, nuclear receptors such as Farnesoid X receptor and peroxisome proliferator activated receptors, Takeda G protein-coupled receptor 5, and the endocannabinoid system, these molecules influence gene expression, cytokine production, and cellular proliferation, thereby shaping the host physiology. Microbial enzymatic transformations, particularly bile acid biotransformation and fatty acid epoxide metabolism, further remodel the lipid mediator network and its biological effects. Disruption of this regulatory axis is associated with increased intestinal permeability, chronic low-grade inflammation, and metabolic dysfunction, contributing to the pathogenesis of metabolic syndrome, non-alcoholic fatty liver disease, inflammatory bowel diseases, and cardiometabolic disorders. From a therapeutic perspective, multicomponent interventions integrating probiotics, prebiotics, post-biotics, dietary modulation, and physical activity may rebalance the lipid mediator profiles and attenuate inflammatory burden. In this context, the microbiota-lipid mediator interface emerges as a translationally relevant biological target for the prevention and management of chronic diseases.
