Cure8 research brief
This review connects enteric sensory neuron dysfunction to symptoms common in IBS and IBD (pain, diarrhea, constipation, dysmotility). Understanding IPAN plasticity could point to new treatment targets that act locally in the gut nervous system rather than centrally or broadly on the immune system.
Researchers studying gut neurobiology, microbiome–immune interactions, and biomarker discovery; clinicians interested in pathophysiology of IBS and IBD; adult patients and caregivers seeking mechanistic explanations for visceral pain and motility symptoms.
The paper argues that IPANs — enteric sensory neurons that regulate local reflexes — show activity changes after inflammatory, microbial, or immune signals.
Those changes can raise or lower sensory gain, which the authors propose could distort enteric reflexes and contribute to symptoms like pain, altered bowel habits, and dysmotility in conditions including IBS and IBD. However, the authors emphasize that most evidence is experimental (animal and cellular models).
There are relatively few studies that selectively manipulate IPANs in disease models to demonstrate that IPAN-specific dysfunction alone causes a gastrointestinal disease phenotype in vivo, and human data are scarce.
The review identifies key unresolved questions about cause versus consequence, interactions with extrinsic afferents, and how microbial/immune signals remodel IPAN identity over time.
This is a narrative review synthesizing experimental literature (animal and cellular studies) and highlights gaps in causal evidence in humans. Findings are mechanistic and hypothesis-generating rather than definitive clinical results.
