What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
9 samples: 3 × BMDMs, M2, vs 3 × BMDMs, M0, vs 3 × BMDMs, TMV-OEG8-Man regulated M2,Groups 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)
Idiopathic pulmonary fibrosis (IPF) is a chronic disease, causing irreversible lung scarring and respiratory failure. CD206+ M2 macrophages play a key role in its progression. In this study, we utilize the pro-inflammatory properties of plant viruses to develop a mannose-modified tobacco mosaic virus nanoparticle (TMV-OEG8-Man), which targets and reprograms profibrotic macrophages to inhibit IPF.
Read the full summary ↓
TMV-OEG8-Man alters the CD206+ M2 macrophage phenotype in vitro, suppressing profibrotic genes (Mrc1, Spp1, Ccr2) and signaling pathways (MAPK, TGF-beta, PI3K-Akt, mTOR, Wnt), thereby reducing the transition of fibroblasts to myofibroblasts. When administered via aerosol, TMV-OEG8-Man achieves prolonged lung retention with minimal systemic exposure. In mice with bleomycin-induced pulmonary fibrosis, a single dose during fibroproliferation attenuated fibrosis progression, increasing survival rate from 50% to 100%, and preserving lung architecture. This study establishes plant viral nanoparticles as a macrophage reprogramming strategy with therapeutic potential for organ fibrosis.

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 GSE309156_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 PRJNA1334241 and SRA study SRP627069. Searching any of these in the dataset finder brings you back here.

Study design
3 × BMDMs, M2, vs 3 × BMDMs, M0, vs 3 × BMDMs, TMV-OEG8-Man regulated M2,

Supports a between-group comparison across 9 samples.

How we read this: 3 replicated groups read from 9 sample titles; they account for 9 of them. 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.
