Cure8 news brief
The work narrows down which genes are likely influenced by Crohn’s disease–associated regulatory DNA in a specific gut immune cell type, helping researchers prioritize targets and understand disease mechanisms.
Researchers in IBD genetics and immunology; clinicians interested in pathogenesis; patients interested in how genetic research may inform future biomarkers or therapies.
Researchers used a miniaturized Capture Hi-C method to profile long-range promoter interactions in type 3 innate lymphoid cells (ILC3s), a scarce gut-associated immune population. This allowed linking noncoding disease-associated variants to the genes they likely regulate in these cells.
About half of the implicated genes were already linked to IBD or Crohn’s disease; others are new candidates. The team highlighted CLN3 — previously known for Batten disease — and report follow-up experiments suggesting it influences inflammatory signaling in ILC3s, illustrating how genome-architecture studies can reveal unexpected gene–disease links.
The study is published in Nature Genetics and represents a basic science advance that refines which genes and cell types may mediate genetic risk for Crohn’s disease.
This is a high-resolution, basic-science study published in Nature Genetics using Capture Hi-C on rare ILC3 cells. It identifies candidate genes but does not itself produce clinical interventions; follow-up validation and translational research are needed.

This study helps move beyond assigning GWAS risk variants to the nearest gene by mapping 3D promoter contacts in gut-enriched ILC3s, so it uncovers new candidate genes and pathways that could explain Crohn’s and other...
The work helps bridge genetic association signals and the specific immune cells in the intestine where they may act, offering new candidate genes and a method that can probe rare cell types important to IBD biology.
ILC3s live in the intestine and help regulate barrier function and inflammation, so mapping how genetic variants affect gene regulation in these rare cells helps connect inherited risk signals to plausible biology for...
