Genetic markers involved in neuroinflammation in Down syndrome: a systematic review.
Article in Dementia & neuropsychologia, 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
The immune system plays a fundamental role in protecting human body organs and tissues; however, when exacerbated, it can contribute to the pathology of various conditions. In the central nervous system, immune cell activation, or neuroinflammation, is a key factor in several neurodegenerative diseases. In Down syndrome (DS), the additional copy of chromosome 21 alters gene expression, potentially enhancing inflammatory processes such as neuroinflammation. Therefore, understanding the genetic factors influencing neuroinflammation in DS is essential for identifying biomarkers and therapeutic targets. Objective: Identify genetic markers involved in neuroinflammatory processes in individuals with DS. Methods: A comprehensive search was conducted in Medical Literature Analysis and Retrieval System Online (Medline) (United States National Library of Medicine [PubMed]), Embase, Cochrane Library, and Latin American and Caribbean Health Sciences Literature (LILACS) databases, and identified ten relevant studies. These studies assessed and compared gene expression between groups with and without DS associated with neuroinflammation. Results: Sixty-three genes and 42 genetic markers associated with neuroinflammation in DS were identified. These genes exhibited expression variations that alter inflammatory responses, suggesting a possible link to the progression of neurodegenerative diseases in this population. Conclusions: The findings highlight the role of neuroinflammation in neurodegenerative disorders in individuals with DS, especially Alzheimer's disease. Some studies indicated that the triplicated genes SOD1, APP, S100B, TREM2, IFNR1, and IFNR2 are directly related to neuroinflammation. Additionally, elevated levels of pro-inflammatory cytokines, such as IL-1, IL-6, IL-10, IFNγ, and TNF-α, and complement proteins like C1q, C3, and C9 suggest an exacerbated activation of the immune response. However, the roles these genes may play in neurodegenerative diseases and in increasing or reducing neuroinflammation remain controversial.
