Summary (written by the submitters)
Systemic inflammation (SI) is a prevalent condition with a high mortality rate1. Survivors of hyperinflammatory state of SI frequently enter a long-lasting immunosuppressive state2 deteriorating their life quality3,4. Due to the extensive heterogeneity in SI etiology, the underlying mechanisms are not well understood. Here, we characterized the short and long-term effects of lipopolysaccharide (LPS)-induced SI (LPS-SI, also called endotoxemia5) on blood monocytes and bone marrow (BM) cells.

Similar to clinical features of SI, we observed a profound but transient acute LPS response, followed by a long-term immunosuppressed state. Single-cell transcriptomic analysis of LPS-SI acute phase unveiled the loss of BM monocytes and the appearance of an inflammatory monocyte-like (i-Mono’s) population, expressing gene programs similar to a cell state identified in early-stage sepsis patients6. We observed impairment of myelopoiesis one week after LPS-SI manifested by a significant loss of intermediate and non-classical monocytes which is associated with reduced expression of interferon type I (IFN-I) genes. We confirm that this compromised myelopoiesis also happens in late-stage sepsis patients. Importantly, IFNb treatment reverted the LPS-induced immunosuppression in monocytes. Our results deepened the knowledge about SI and its long-lasting effects on myelopoiesis, substantiating the importance of IFN-I in the pathophysiology of SI-induced immunosuppression.

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 GSE212092_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 PRJNA873948. Searching any of these in the dataset finder brings you back here.

Study design
18 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 18 sample titles: 18 distinct titles with little repetition. 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.
