What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Circulating monocytes upregulate CD52 and sustain innate immune function in cirrhosis unless acute decompensation emergesJournal of hepatology · 2025
Summary (written by the submitters)
Background & Aims: Infectious complications determine the prognosis of cirrhosis patients. Their infection susceptibility relates to the development of immuneparesis, a complex interplay of different immunosuppressive cells and soluble factors. Mechanisms underlying the dynamics of immuneparesis of innate immunity remain inconclusive.

We aimed to dissect the heterogeneity of circulating monocyte states in different cirrhosis stages, and pursued the function of selected differentially expressed (DE) genes. Methods: We systematically investigated circulating monocytes in health, compensated and not-acutely decompensated (NAD) cirrhosis using single cell RNA sequencing. Selective genes were confirmed by flow cytometry and diverse functional assays on monocytes ex vivo. Results: We identified seven monocyte clusters. Their abundances varied between cirrhosis stages, confirming previously reported changes i.e. reduction in CD14lowCD16++ and emergence of M-MDSC in advanced stages. DE genes between health and disease and among stages were detected, including for the first time CD52. CD52-expression on monocytes significantly enhanced throughout compensated and NAD cirrhosis. Heretofore the biological significance of CD52-expression on mon enhanced migratory potential, increased cytokine production, but poor T cell activation. Following acute decompensation (AD), CD52 was cleaved by elevated phospholipase C (PLC), and soluble CD52 (sCD52) was detected in the circulation. Inhibition and cleavage of CD52 significantly suppressed monocyte functions ex vivo and in vitro, and the predominance of immunosuppressive CD52low circulating monocytes in patients with AD was associated with infection and low transplant-free survival. Conclusion: CD52 may represent a biologically relevant target for future immunotherapy. Stabilising CD52 may enhance monocyte functions and infection control in the context of cirrhosis, guided by sCD52/PLC as biomarkers indicating immuneparesis.ocytes remained unknown.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE263100_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1095842. Searching any of these in the dataset finder brings you back here.

Study design
9 × patient vs 6 × healthy_control

Supports a case/control comparison: 9 samples read as cases, 6 as controls.

How we read this: 2 replicated groups read from 15 sample titles; they account for 15 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
