TSP50 in Neural Stem Cells Regulates Aging-Related Cognitive Decline and Neuroinflammation by Altering the Gut Microbiota.

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 a process of gradual decline in physical and cognitive function and is a major risk factor for mortality. Despite the increasing number of relevant studies, the mechanisms regulating the aging process have not been fully elucidated. Genetic factors have long been recognized as key factors in controlling the rate of aging. Testes-specific protease 50 (TSP50) has been shown to be involved in the regulation of embryonic development and intestinal homeostasis, but its role in the regulation of aging remains unclear. Here, we showed that TSP50 expression was reduced in the hippocampus of both aged humans and mice. TSP50 deficiency in neural stem cells (NSCs) drove accelerated aging in mice, characterized by exacerbated age-related cognitive impairments and significantly elevated neuroinflammation. Notably, aged mice with NSCs-specific knockout of TSP50 exhibited impaired intestinal mucosal barriers, dysbiosis of gut microbiota, and a marked reduction in the production of short-chain fatty acids (SCFAs). Restoring gut microbial ecology using fecal microbiota transplantation (FMT) and overexpressing TSP50 successfully alleviated aging-associated cognitive decline and neuroinflammation. Taken together, our study suggests that TSP50 plays a critical role in the aging process and identifies gut microbiota as a pivotal mediator of TSP50's influence on age-related cognitive decline and neuroinflammation. These findings highlight the potential therapeutic value of targeting TSP50 and gut microbiota for aging, offering insights into aging mechanisms and interventions for aging-related neurodegenerative diseases.
