Single-cell RNA-seq · human · 10 samples

What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.
Organism
Homo sapiens (human)
Samples
10 samples: 4 × Entorhinal CERAD_0 Braak_0 vs 4 × Entorhinal CERAD_B Braak_IIGroups 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)
Neurons located in the layer II of the entorhinal cortex (ECII) are the primary site of pathological tau accumulation and neurodegeneration at preclinical stages of Alzheimer's disease (AD). Exploring the alterations that underlie the early degeneration of these cells is essential to develop therapies that delay disease onset. Here we performed cell–type specific profiling of the EC at the onset of human AD neuropathology.
Read the full summary ↓
We identify an early response to amyloid pathology by microglia and oligodendrocytes. More importantly, we find that the Reelin signaling pathway is already impaired at this early disease stage, particularly in ECII neurons. This indicates that dysregulation of this pathway, with emerging genetic association with AD, plays a pivotal role in the selective vulnerability of the EC and in the onset of AD neuropathology.

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 GSE287652_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 PRJNA1214196 and SRA study SRP558999. Searching any of these in the dataset finder brings you back here.

4 × Entorhinal CERAD_0 Braak_0 vs 4 × Entorhinal CERAD_B Braak_II

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 8 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.
