What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.

Mus musculus (mouse)
Samples
15 samples: 15 samples, each with a distinct title — no replicated groupsGroups 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)
This study is part of the immgenT Open Source Project, specifically from IGT35, which focuses on characterizing T cells in the B16.gp33 melanoma model following adoptive cell therapy (ACT) and immune checkpoint blockade.
Read the full summary ↓
T cells were isolated from tumors and draining inguinal lymph nodes of C57BL/6J male mice (7–8 weeks old) subjected to subcutaneous implantation of B16.gp33 melanoma cells, followed by adoptive cell transfer treatment with intravenous transfer of P14 and pmel T cells, and treatment with either isotype control antibodies or a combination of anti-PD-1 and anti-4-1BB antibodies. Samples were collected at day 14 post post-tumor implantation (1 day post-final antibody treatment). The study targeted all CD3+ T cell populations, including transgenic P14 and pmel T cells

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 GSE311344_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 PRJNA1368984 and SRA study SRP648784. Searching any of these in the dataset finder brings you back here.

Study design
15 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 15 sample titles: 15 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.
