Summary (written by the submitters)
CD8+ T cells have been categorized as an adaptive lymphocyte, based on their ability to recognize specific foreign antigens and mount memory responses. However, neonatal and adult CD8+ T cells are derived from distinct HSC progenitors, which may alter the roles they play during infection. Here, we demonstrate that neonatal CD8+ T cells can be activated by innate cytokines alone and protect the host from a variety of unrelated pathogens in the absence of TCR signaling.
Read the full summary ↓
Using a multi-omics approach, we found that neonatal CD8+ T cells are highly responsive to innate cytokines because they can rapidly undergo chromatin remodeling, resulting in the usage of a distinct set of enhancers that are more commonly found in innate-like T cells. We also identified a key gene regulatory axis (Bach2/AP1) that is differentially utilized by neonatal and adult CD8+ T cells to toggle their responsiveness to innate cytokines. Importantly, the developmental switch between innate and adaptive functions in the CD8+ T cell compartment is not mediated by a change in the maturation of individual cells along a linear axis, but rather by changes in the abundance of distinct subsets of cells. Collectively, our findings provide support for the layered immune hypothesis and indicate that the CD8+ T cell compartment is more phenotypically diverse than previously thought.

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 GSE261140_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 PRJNA1085376 and SRA study SRP494027. Searching any of these in the dataset finder brings you back here.

Study design
21 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 21 sample titles: 21 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.
