Human Endogenous Retrovirus K in Astrocytes Is Altered in Parkinson's Disease.
Article in Movement disorders : official journal of the Movement Disorder Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundParkinson's disease (PD) is the most common neurodegenerative movement disease. Human endogenous retroviruses (HERVs) are proviral remnants of ancient retroviral infection of germ cells that now constitute about 8% of the human genome. Under certain disease conditions, HERV genes are activated and partake in the disease process. However, virtually nothing is known about the pathological relationship, if any, between HERV and PD.
objectiveThe objectives of this study were to unravel the pathological relationship between human endogenous retrovirus K (HERV-K) and PD, determine the localization of HERV-K in the brain, determine whether HERV-K levels are altered in PD brain and blood, and examine whether HERV-K could serve as a biomarker for PD.
methodsIn situ HERV-K and glial fibrillary acidic protein (GFAP) expression in the superior frontal and fusiform cortices of PD and control brain were analyzed using immunofluorescence and confocal microscopy. HERV-K load and copy number in PD and control blood were measured by digital droplet polymerase chain reaction and GFAP by single-molecule array. HERV-K load was analyzed in relation to the Hoehn and Yahr Scale and Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III.
resultsHERV-K is predominantly expressed in astrocytes and colocalized with astrocytic GFAP, with decreased expression of both HERV-K and GFAP in PD brain compared with controls. Consistent with this, HERV-K levels were decreased in PD blood compared with controls and were correlated to blood GFAP levels. HERV-K levels were inversely correlated to PD severity and duration.
conclusionsThese findings suggest that HERV-K is related to astrocyte function and to PD progression, and that HERV-K could be neuroprotective. © 2025 The Author(s). Movement Disorders published by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society.
