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.
Organism

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.
Paper
Disease activity drives divergent epigenetic and transcriptomic reprogramming of monocyte subpopulations in systemic lupus erythematosusAnnals of the rheumatic diseases · 2024
Summary (written by the submitters)
Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by systemic inflammation that involves various immune cell types. Monocytes play a central role in promoting and regulating inflammation. Peripheral blood classical monocytes subsequently differentiate into intermediate monocytes and then non-classical monocytes, assuming diverse roles and undergoing changes in their proportions during physiological immune responses and pathological conditions, including SLE.

In this study, we obtained the epigenetic and transcriptomic profiles of these three monocyte subsets in an SLE cohort. We found different common and subset-specific alterations. While SLE classical monocytes had a stronger proinflammatory profile with an important interferon influence priming them towards macrophage differentiation, non-classical monocytes had a phenotype related to T cell differentiation regulation, with several indications pointing towards a Th17 promoting behavior. Integration of these bulk datasets with single-cell RNA-seq data of an SLE cohort shed light on the heterogeneity of our monocytes, confirming the interferon signature profile of classical monocytes and pointing towards intermediate and non-classical populations associated with exacerbated complement activation pathways, among others. Our results indicate a subversion of the epigenome and transcriptome in monocyte differentiation toward non-classical subsets in SLE, involving the STAT1 pathway and impacting function in relation to disease activity.

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 GSE249619_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 PRJNA1049831 and SRA study SRP476492. Searching any of these in the dataset finder brings you back here.
