Targeting Astrogliosis in the Retrotrapezoid Nucleus: A Novel Approach to Ameliorate Respiratory Dysfunction and Alzheimer's Pathology in Mice.
Article in Aging and disease, 2024. 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
Alzheimer's disease (AD), a leading cause of dementia, is associated with significant respiratory dysfunctions. Our study explores the role of astrogliosis in the brainstem retrotrapezoid nucleus (RTN), a key breathing regulatory center, and its impact on breathing control and AD pathology in mice. Using Tg-2576 AD and wild-type mice, we investigated the effect of silencing the transforming growth factor-beta receptor II (TGFβR II) in the RTN. We performed behavioral tests, including the Barnes maze and novel object recognition test, along with whole-body plethysmography to assess breathing disorders. Our results showed that AD mice exhibited increased apneas and cognitive impairment, which were significantly mitigated following TGFβR II gene silencing. Immunohistochemistry revealed elevated levels of GFAP and TGFβR II in the RTN of AD mice, which were reduced post-gene silencing, alongside a decrease in amyloid-beta expression in the cortex and hippocampus. These findings suggest that targeting astrogliosis and improving respiratory control may offer a novel therapeutic avenue for managing Alzheimer's disease. Our study provides the first mechanistic insights into how TGFβ signaling influences both respiratory control and AD pathogenesis, highlighting the potential benefits of stabilizing breathing patterns in AD treatment.
