Analysis of Hyperexpanded T Cell Clones in SARS-CoV-2 Vaccine-Associated Liver Injury by Spatial Proteomics and Transcriptomics.
Article in Liver international : official journal of the International Association for the Study of the Liver, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND AND
aimsSARS-CoV-2 vaccine-associated liver injury (SVALI) is a rare event and its pathophysiology remains unclear. Previous studies have found an oligoclonal CD8+ T cell infiltrate and SARS-CoV-2 spike antigen-specific T cells in the liver of patients with SVALI. Therefore, we aimed to characterise the immune infiltrate in a liver explant from a patient with severe SVALI.
methodsT cell receptor sequencing, a novel combined multiplex immunofluorescence (mIF)-RNA in situ hybridisation (RISH) approach, and single cell spatial transcriptomics with the Xenium in situ platform were used to identify, track and characterise specific T cell clones in this liver sample.
resultsT cell repertoire analysis revealed hyperexpanded clones with CDR3 sequences similar to previously identified SARS-CoV-2 spike antigen-specific T cells. The hyperexpanded clones were localised throughout the whole liver, but the concentration was higher at the portal interface. Many hyperexpanded T cells expressed cytotoxic granzymes A, B and K, but also tissue-resident markers such as CXCR6, CD69 and KLRB1.
conclusionsSpatial proteomics and spatial transcriptomics techniques allowed the localisation and characterisation of hyperexpanded CD8+ T cell clones at single cell level. They exhibited cytotoxic and tissue-resident memory properties, suggesting their involvement in the pathogenesis of SVALI.
