Summary (written by the submitters)
Tuberculosis (TB) remains one of the leading causes of death from a single infectious agent worldwide, yet the host pathways that regulate antigen presentation and lung inflammation during Mycobacterium tuberculosis (Mtb) infection are incompletely defined. Sorting nexin 5 (SNX5) is a phox homology (PX) and bin, amphiphysin, rvs (BAR) domain protein best known for roles in endosomal trafficking, antigen processing, and antiviral host defense, but its contribution to immunity during Mtb infection is unknown.

Here, we show that SNX5-deficient mice exhibit markedly increased mortality following low-dose aerosol infection despite unchanged pulmonary bacterial burden compared to wild-type mice. Snx5-/- mice developed exacerbated lung inflammation without major alterations in immune cell recruitment. In macrophages, Snx5-/- did not affect phagocytosis, vacuolar maturation, intracellular bacterial control, or global transcriptional responses to Mtb, but was required for efficient MHC class II antigen presentation. Snx5 deficiency reduced antigen degradation, limited peptide loading onto MHC-II and impaired activation of antigen-specific CD4+ T cells without altering surface MHC-II abundance or expression of costimulatory molecules. Together, these findings identify SNX5 as a previously unrecognized regulator of MHC-II peptide loading that shapes inflammatory outcomes during pulmonary Mtb infection, highlighting a role for endosomal sorting machinery in immunity to intracellular pathogens.

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 GSE317798_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1415276 and SRA study SRP667989. Searching any of these in the dataset finder brings you back here.
