Immune Cell Characteristics in a Gut-Kidney Axis-Induced Mouse Model of IgA Nephropathy: The Upregulated Dendritic Cells and Neutrophils.
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: IgA nephropathy (IgAN) is the leading type of primary glomerulonephritis, significantly contributing to chronic kidney disease (CKD) and renal failure. The pathogenesis of IgAN is the multi-hit hypothesis regarding overproduction and accumulation of galactose-deficient (Gd-IgA1). Recent findings have revealed gut microbiota dysbiosis and immune responses are essential in the development of IgAN, attracting increasing attention. This study aimed to map mucosal immune cells in IgAN influenced by gut microbiota, investigating the role of innate immune cells in kidney damage. Methods: Fecal samples were acquired from both patients and controls for subsequent animal experiments. Mice received a broad-spectrum antibiotic cocktail to eliminate their intestinal microflora, followed by a gavage with fecal microbiota from clinical individuals. Murine intestinal and kidney tissues were collected for flow cytometry. Intestine and kidney histopathology, immunofluorescence, and inflammatory cytokine expression were assessed in the murine models. The mucosal epithelium's structure and function, along with the innate immune cell response, were analyzed. Results: Mice exhibited the IgAN phenotype following colonization with gut microbiota from IgAN patients. These mice (IgAN-FMT mice) showed renal dysfunction and increased pathology of tissue injury in both intestine and kidneys. IgAN-FMT mice showed heightened pro-inflammatory cytokine (IL-6 and TNF-α) activity, greater antibody (IgA and complement C3) deposition and decreased expression of mucosal barrier protein (ZO-1, Occludin) compared to the control group. Furthermore, CD11c Conclusion: The gut-kidney axis, including microbiota homeostasis and innate immune cell response, contributes to the pathogenesis of IgAN. Gut dysbiosis and hyperactivated immune cells like CD11c
