Reduced Type-I Interferon by Plasmacytoid Dendritic Cells and Asthma in School-Aged ChildrenAllergy · 2026
Summary (written by the submitters)
Allergic sensitisation and reduced ability to respond to viral infections may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells (pDC) are rare immune cells that produce type I interferons (IFN-I) and play a key role in orchestrating immune responses against viruses. To further evaluate the function of pDC in children with asthma, we studied a subset of 71 children from the Early Life Lung Function (ELLF) cohort at the age of 7-years.

As part of the ELLF study, participants were characterised for atopic sensitisation, viral infection history and lung function testing. pDC responses to a TLR7/8 agonist were assessed in the presence or absence of anti-IgE using an in vitro assay. Responses were evaluated utilising flow cytometry, multiplexed cytokine assays and transcriptional analysis of isolated pDC. pDC responses varied considerably across individuals and those who responded with IFN-I following stimulation showed lower proportion of asthma compared to those who responded with TNF-only. A TNF-only response was associated with increased atopy and reduced upregulation of IFN-associated genes. Anti-IgE stimulation reduced pDC activation and the reduction was associated with baseline expression of the IgE receptor (FceR1). A reduction in a gene module centralised around genes such as TPM2, LILRA4 and CLEC4C was also observed. Together, these findings suggest that pDC responses are variable, associated with asthma and appear influenced by environmental stimuli. This response thus appears to be an important aspect of asthma pathology in children.

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 GSE289352_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 PRJNA1222551 and SRA study SRP563331. Searching any of these in the dataset finder brings you back here.
