What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.

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)
Neurofilament light chain (NfL) is a neuron-specific cytoskeletal protein that provides structural support for axons and is released into the extracellular space following neuronal injury. While NfL has been extensively studied as a disease biomarker, the underlying release mechanisms and role in neurodegeneration remain poorly understood.
Read the full summary ↓
Here, we find that neurons secrete low baseline levels of NfL, while neuronal damage triggers calpain-driven proteolysis and release of fragmented NfL. Secreted NfL activates microglia cells, which can be blocked with anti-NfL antibodies. We utilize in vivo single-cell RNA sequencing to profile brain cells after injection of recombinant NfL into the mouse hippocampus and find robust macrophage and microglial responses. Consistently, NfL knock-out mice ameliorate microgliosis and delay symptom onset in the SOD1 mouse model of amyotrophic lateral sclerosis (ALS). Our results show that released NfL can activate myeloid cells in the brain and is, thus, a potential therapeutic target for neurodegenerative diseases.

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 GSE287862_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 PRJNA1214826 and SRA study SRP559467. Searching any of these in the dataset finder brings you back here.
