Cure8 research brief
Spatial mapping of immune niches in refractory UC identified tissue signatures (neutrophil-rich ulcer-bed niches and TLS/plasma-cell programmes) that were associated with failure to respond to biologic drugs across adult datasets, which could help explain and eventually predict who will not benefit from certain biologics.
Clinicians and researchers studying UC treatment response and biomarker development; adult patients with medically refractory UC and their caregivers.
This study used high-resolution spatial transcriptomics (10x Visium HD) on full-thickness, surgically resected colon samples from a small set of adults with medically refractory ulcerative colitis and controls to map immune–stromal niches across the tissue.
The authors identified an “Acute Neutrophil Niche” at ulcer beds, tertiary lymphoid structure (TLS)–associated humoral programmes in submucosa, and plasma-cell survival signalling; they derived niche-based signatures that were associated with biologic non-response across several adult cohorts and validated some cellular findings in a mouse colitis model.
The paper suggests these spatial niche signatures could help explain why some patients do not respond to anti-TNF or anti-integrin biologics and might inform future biomarker-driven treatment selection, but prospective clinical validation is still needed.
Results are based on high-resolution spatial transcriptomics of a small set of resected samples and cross-cohort analyses; prospective validation is required before these signatures can guide treatment decisions.
