An optimized method to visualize lipid droplets in mouse brain tissue.
Article in Cell reports methods, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lipid droplets (LDs) are lipid-storage organelles that have gained interest in neurodegenerative diseases, yet their physiological role in the brain is not fully understood. Classical LD detection using lipophilic dyes like BODIPY 493/503 (BD493) or antibodies against LD coat proteins typically reveals few LDs in healthy brain tissue. In contrast, our recently developed endogenous LD-reporter mouse showed numerous LDs in the developing and adult brain without staining. To understand this discrepancy, we examined how tissue preparation and detergent influence LD detection. We found that BD493 performs poorly in brain tissue, whereas other lipophilic dyes allow visualization of many LDs. Antibody-based detection is sensitive to tissue pretreatment but can reveal similar LD numbers as the LD-reporter mouse. We here present an optimized protocol, demonstrating that LDs are abundant in healthy young and aged brains, with larger LDs in aged mice. However, LD detection in aged brains requires caution due to strong LD-like autofluorescence.
