Large-scale effects of prenatal inflammation and early life circadian disruption in mice: Implications for neurodevelopmental disordersBrain, behavior, and immunity · 2025
Summary (written by the submitters)
Background: Around 80% of individuals with neurodevelopmental disorders (NDDs) such as schizophrenia and autism spectrum disorders experience disruptions in sleep/circadian rhythms. We explored whether prenatal infection, an established risk factor for NDDs, and environmental circadian disruption synergistically induced sex-specific deficits in mice.

Methods: A maternal immune activation (MIA) protocol was used by injecting pregnant mice with a viral mimic poly IC (9.5) or saline. Then, juvenile/adolescent offspring (3-7 weeks old) were subjected to either standard lighting (12:12LD) or constant light (LL). Results: We found interactions of the two factors on behaviors related to cognition, anxiety, and sociability. Notably, poly IC exposure led to a more activated profile of hippocampal microglia in males only, while LL diminished these effects. Using RNA sequencing in the dorsal hippocampus, we found that poly IC exposure led to several differentially expressed genes in males (but not females), and fewer differential expressed genes were observed after LL exposure in both sexes. Using the WGCNA analysis, we found that modules of co-expressed genes associated with LL were enriched for pathways involved in synaptic transmission and vesicle mediated transport. Not only were many of these genes related to sleep/circadian rhythms and NDDs in humans, but they were also related to neurotransmission, suggesting that LL exerts its effects by disrupting the expression of proteins required for efficient neurotransmitter release. Conclusions: Understanding the link between circadian disruption and MIA is crucial for NDD due to the widespread exposure to environmental circadian disruption in society and the high transmission of viral infections among pregnant individuals.

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 GSE255938_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 PRJNA1077274 and SRA study SRP490000. Searching any of these in the dataset finder brings you back here.
