Summary (written by the submitters)
CD4+ T cell-mediated control of tuberculosis (TB) requires recognition of macrophages infected with Mycobacterium tuberculosis (Mtb). Yet not all Mtb-specific T cells recognize infected macrophages. Using infected monocyte-derived macrophages (MDMs) and autologous memory CD4+ T cells from individuals with latent Mtb infection (LTBI), we isolate and quantify CD4+ T cells activated in response to infected macrophages.
Read the full summary ↓
We use T cell antigen receptor (TCR) sequencing to determine the total and unique Mtb-specific TCR clonotypes linked to recognition of infected macrophages, and find that a subset required exogenous antigen exposure, suggesting incomplete recognition. Clonotypes specific for multiple Mtb antigens, and other pathogens, were also identified. We use bulk TCRb deep sequencing from total CD4+ T cells isolated from 10x106 PBMCs from each participant to determine the natural circulating frequencies of relevant TCR clonotypes. We used single-cell RNA sequencing (scRNAseq) to examine the effector functions of CD4+ T cells in response to infected macrophages. Mtb-specific clonotypes expressed signature effector functions dominated by IFNg, TNF, IL-2, and GM-CSF or chemokine production and signaling. We propose TB vaccines that elicit T cells specific for T7SS substrates, recognize infected macrophages, and express canonical effector functions will offer protection against TB.

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 GSE305300_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 PRJNA1305204 and SRA study SRP608586. Searching any of these in the dataset finder brings you back here.

Study design
36 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 36 sample titles: 36 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.
