Characterization of jejunal enteroids in human obesity; a model for studying GLP-1 cells.
Article in International journal of obesity (2005), 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
objectivesObesity and type 2 diabetes (T2D) are associated with altered secretion of enteroendocrine hormones, including the glucagon-like peptide-1 (GLP-1). The mechanisms underlying this dysregulation remain poorly understood, partly due to the rarity of enteroendocrine cells (EECs) and technical difficulties in humans. Our aim was to generate an in vitro human jejunal enteroids (HJEs) derived from individuals with obesity and T2D as a simplified intestinal epithelium in a controlled environment, in order to explore GLP-1 secretion in metabolic diseases. SUBJECTS AND
methodsHJEs were obtained from jejunum fragments sampled during gastric bypass surgery in individuals with severe obesity and normoglycemia (Ob, n = 12), prediabetes (ObPreD, n = 12), or T2D (ObD, n = 10). HJEs were characterized through gene and protein expression analyses and immunofluorescence. To promote the EEC lineage, HJEs were treated with the Notch pathway inhibitor DAPT. Active GLP-1 secretion was assessed by ELISA.
resultsHJEs were successfully generated whatever the metabolic group Ob, ObPreD, ObD, exhibiting epithelial cell lineages and expressing critical genes involved in GLP-1 cell lineage, biosynthesis, and secretion. HJEs secreted active GLP-1 in response to both low and high glucose concentrations, regardless of subject metabolic status. However, HJEs from individuals with severe obesity and T2D exhibited a reduced capacity to release GLP-1 in response to high glucose concentrations compared to those from individuals with severe obesity or with obesity and prediabetes.
conclusionsHJEs represent a robust human-derived model to investigate EEC function and GLP-1 secretion in metabolic diseases. While HJEs retain functional GLP-1-producing cells, their secretory capacity is impaired in the presence of T2D, confirming functional endocrine alterations. These findings support the use of HJEs in preclinical studies targeting enteroendocrine dysfunction.
