Summary (written by the submitters)

The identification of the most appropriate T-cell subset to ensure optimal persistence and anti-tumor activity is a major goal of cancer immunotherapy. We identified a novel post-mitotic CD45RA+CD62L+ T cell subpopulation (TTN), generated in vitro upon activation of naïve T (TN) cells with beads conjugated to anti-CD3 and anti-CD28 antibodies.

This cell population is highly proliferative, produces low levels of IFNg and cytotoxic molecules, and requires IL-7 and IL-15 for in vitro expansion. To investigate whether this cell population represents a novel T-cell subset, we compared the transcriptomic profile of TTN with that of other T-cell subsets, namely naturally occurring TN and central memory (TCM) and manipulated cells of TCM origin (TTCM).

Download · which file do I need?

Direct links to NCBI, 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.

All supplementary files ↗

3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE41909_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

Whole study · RAW.tar ↓

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.

Also filed as BioProject PRJNA178466. Searching any of these in the dataset finder brings you back here.
