Human and mouse regenerative macrophages enhance beta cell survival, function, and proliferation.
Article in Islets, 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
aimsType 1 diabetes is caused by immune-mediated destruction of beta cells. Interestingly, individuals with long-standing type 1 diabetes have residual beta cells, suggesting regenerative mechanisms may help beta cell survival. Islet-resident macrophages have an important role in diabetes, and can adopt a tissue-regenerating phenotype that may support beta cells. However, the roles of macrophages in beta cell survival, function, and proliferation remain poorly defined. This study aimed to elucidate how macrophage subtypes influence beta cell survival, function, and proliferation.
methodsMouse and human islets were isolated from the pancreas and co-cultured
resultsWe found that regenerative, but not pro-inflammatory, macrophages enhanced beta cell survival and function through mechanisms that did not require direct cell contact. Direct contact between macrophages and islets promoted a macrophage regenerative phenotype characterized by increased CD206 expression and secretion of anti-inflammatory factors. Additionally, regenerative macrophages promoted beta cell proliferation in the presence of harmine.
conclusionsOur findings demonstrate that regenerative macrophages support pancreatic beta cell survival, function, and proliferation. Harnessing the regenerative properties of macrophages could offer a novel strategy to promote beta cell survival and function.
