Listeria-infected macrophages promote biomechanical alterations in endothelial cell monolayers for transmigrationCell reports · 2026
Summary (written by the submitters)
We sought to identify changes in gene expression that occur when endothelial cells in monolayer interact with either uninfected or Listeria monocytogenes-infected macrophages. To that end we seeded HUVEC in monolayer and either exposed them to nothing, or to uninfected PMA-differentiated macrophage-like U937, or to Listeria monocytogenes-infected PMA-differenitated U937.

At 8 or 24 hours post U937 exposure (hpe), we washed the samples thoroughly to remove U937 and then collected the mRNA to to perform RNA-Sequencing and gene expression profiling for the six conidtions described. By analyzing the differentially expressed genes between all conditions we find a significant number of up- or down-regulated genes related to innate immune signaling in both (un)infected U937 exposed HUVEC as compared to control unexposed HUVEC, irrespective of the time post-exposure. For example we found significant upregulation of genes related IL-17, NF-kB and TNF related signaling pathways, though to a lesser degree for HUVEC exposed to uninfected U937 as compared to bacterially infected. Interestingly, we found that only HUVEC exposed to uninfected but not infected U937 and only at 8hpe showed significant upregulation of genes related to focal adhesions and regulation of the actin cytoskeleton. We found that consistent with alterations in the dynamics of HUVEC under this condition, which show a significant rise in the traction on monolayer stresses they exert. At later times post-exposure (i.e., 24 hpe) were these changes in gene expression are not present anymore, HUVEC dynamics are also identical irrespective of whether they were exposed or not to (un)infected U937. Thus the RNA sequnecing results at 8 hpe that reveal upregulation of genes related to focal adhesions and the actin cytoskeleton for uninfected U937 exposed HUVEC match with the results of traction force and monolyaer stress microscopy that reveal strong enhancement of these forces over the first 10 hpe and which are absent in the other two conditions or at the later time point of 24 hpe.

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 GSE296345_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 PRJNA1258956 and SRA study SRP583142. Searching any of these in the dataset finder brings you back here.

Study design
24 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 24 sample titles: 24 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.
