Paper
Altered DNA methylation underlies monocyte dysregulation and immune exhaustion memory in sepsisCell reports · 2024
Summary (written by the submitters)
Innate immune memory is the process by which pathogen exposure elicits cell-intrinsic states to alter the strength of future immune challenges. Such altered memory states drive monocyte dysregulation during sepsis, promoting pathogenic behavior characterized by pro-inflammatory, immunosuppressive gene expression and emergency hematopoiesis.
Read the full summary ↓
Epigenetic changes, notably via histone modifications, have been shown to underlie innate immune memory, but the contribution of DNA methylation remains poorly understood. Using an ex vivo sepsis model, we discovered broad changes in DNA methylation throughout the genome of exhausted monocytes, including at several genes implicated in immune dysregulation during sepsis and Covid-19 infection (e.g. Plac8). Methylome reprogramming is driven in part by Wnt signaling inhibition in exhausted monocytes, and can be reversed with DNA methyltransferase inhibitors, Wnt agonists, or immune training molecules. These changes are recapitulated in septic mice following cecal slurry injection, supporting the involvement of DNA methylation in acute and long-term monocyte dysregulation during sepsis.

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 GSE253201_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1064414 and SRA study SRP483555. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
