What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

Samples
28 samples: 8 conditions, mostly in triplicateGroups are read from the sample names, not from the paper. Check the list below.
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.
Summary (written by the submitters)
Z-DNA is a non-canonical structure capable of activating innate immune signaling through Z-DNA-binding protein 1 (ZBP1). However, the functional significance of ZBP1-mediated detection of Z-DNA in Alzheimer's disease (AD) remains poorly defined. Here, we found that ZBP1 is amplified in AD microglia, triggering innate immune response and neuroinflammation through sensing Z-form mitochondrial DNA (mtDNA).

We show that fragmented oxidized mtDNA (Ox-mtDNA), produced during oxidative stress, cleaved by mitochondria nucleases, and released via the mPTP-VDAC channel, serves as the source of Z-form mtDNA. We demonstrated that Z-DNA-activated ZBP1 engages RIPK1, promoting RIPK1 kinase activation and RIPK1-kinase dependent transcription of pro-inflammatory molecules and intracellular inflammatory signaling mediators for various inflammatory pathways. Deletion of ZBP1 or genetic inhibition of RIPK1 kinase limits the innate immune response, neuroinflammation, Aβ pathology, and behavioral deficits in an AD mouse model. Our findings demonstrate that innate immune signaling by Z-form mtDNA-ZBP1-RIPK1 axis drives microglia-mediated neuroinflammation in AD, providing new insights into the immune mechanisms underlying AD pathogenesis and revealing a potential therapeutic avenue for AD.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE277245_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Supports a between-group comparison across 24 samples.

How we read this: 8 replicated groups read from 28 sample titles; they account for 24 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.
