CD47 signaling in aging and age-related diseases: mechanisms, challenges, and therapeutic opportunities.
Review in Biogerontology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Aging is marked by progressive dysfunction in cellular maintenance pathways, including mitochondrial impairment, reduced autophagic capacity, and accumulation of senescent cells, which contribute to chronic low-grade inflammation. The transmembrane protein CD47 best known for delivering a "don't eat me" signal through SIRPα is increasingly recognized as an important modulator of several aging-related processes. Its upregulation in aged or inflamed tissues can inhibit the clearance of damaged or senescent cells, reinforce inflammatory signaling through pathways such as NF-κB, and influence metabolic and autophagy-related regulation in a context-dependent manner. This review synthesizes current evidence identifying CD47 as an integrative node that intersects with multiple hallmarks of aging. We examine its roles across cardiovascular, neurodegenerative, and metabolic pathologies, and evaluate the emerging therapeutic landscape targeting the CD47-SIRPα axis. Although CD47 blockade has shown promise in enhancing immune clearance and improving tissue homeostasis, clinical translation remains challenged by on-target toxicities such as anemia and by age-dependent variability in immune responsiveness. Targeting CD47 therefore represents a mechanistically grounded but inherently complex strategy for mitigating age-related functional decline.
