Summary (written by the submitters)
The formation of antigen-specific memory CD8+ T cells is one of the most important features of the adaptative immune system, allowing the establishment of long-term protection against secondary infections. Although emerging evidence suggests that metabolic reprogramming is crucial for memory T cell differentiation and survival, the underlying mechanisms that drive metabolic rewiring needed for memory T cells remain unclear.

Here, we found that the nuclear receptor peroxisome proliferator-activated receptor-beta/delta (PPARβ/δ) was upregulated to instruct the metabolic reprogramming, including downregulation of aerobic glycolysis and the promotion of oxidative metabolism and fatty acid oxidation, that occurs during the transition toward the establishment of central memory CD8+ T cells. Mechanistically, the exposure to interleukin-15 (IL-15) and expression of T cell factor 1 (TCF1) could coordinately activated the PPARβ/δ pathway during acute viral infection and chronic antigen exposure contexts, counteracting apoptosis induced by antigen clearance and metabolic stress. Together, our work indicates that PPARβ/δ is a master metabolic regulator orchestrating the metabolic reprogramming required for the establishment of a metabolic profile favorable for T cells longevity.

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 GSE268419_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 PRJNA1117063 and SRA study SRP510159. Searching any of these in the dataset finder brings you back here.
