How neutrophil traps (NETs) and the PAD4 enzyme affect gut healing in IBD
Role of neutrophil extracellular traps (NETs) in Inflammatory bowel disease
Researchers are looking at whether the enzyme PAD4 and the neutrophil traps it creates help protect the gut in people with Crohn’s disease or ulcerative colitis.

What this research studies
This work focuses on inflammatory bowel disease (IBD) and the role of neutrophils, an immune cell that rushes to inflamed gut tissue. The team will study how the enzyme PAD4 helps neutrophils release DNA-based traps (NETs) and a modified protein called H3Cit. Using mouse models and molecular experiments, they will test how PAD4 and NETs affect gut inflammation, leakage of neutrophil proteins, and interactions with gut bacteria. The goal is to map how these processes influence tissue damage and repair in IBD.
Who could benefit from this research
Good fit: People with Crohn’s disease or ulcerative colitis—especially those with active inflammation or frequent flares—would be most relevant to follow or participate in related future work.
Not a fit: People without inflammatory bowel disease or whose symptoms are driven primarily by non-immune causes are unlikely to benefit directly from this line of research.
Why it matters
Potential benefit: If successful, the findings could point to new ways to protect the gut lining and reduce inflammation in Crohn’s disease and ulcerative colitis.
How similar studies have performed: Previous laboratory studies have linked NETs and PAD4 to inflammation and gut damage, but using PAD4/NET biology to protect the gut is a relatively new idea that needs more testing.
