Cure8 research brief
The paper suggests a molecular link (RHBDF2–ADAM17–TNFα) between ulcerative colitis and blood–brain barrier disruption, which could explain some neurological comorbidities of UC and identify targets for future therapies.
Researchers on IBD and neuroinflammation; clinicians managing UC patients with neurological symptoms; patients interested in IBD-related brain risks
Researchers combined multi-cohort human transcriptome meta-analysis with single-cell RNA-seq and genetic causal inference (SMR) to find genes up-regulated in both UC colon tissue and models of BBB disruption. RHBDF2 emerged as a shared, cell-type-specific mediator (epithelial cells in colon; endothelial cells at the BBB) linked to ADAM17 and TNFα signaling.
In mice with DSS-induced colitis, preventive treatment with the ADAM17 inhibitor GW280264X reduced intestinal inflammation, lowered brain markers (Rhbdf2, Adam17, Tnfα), and decreased Evans blue dye leakage into the brain, supporting a functional role for this axis in BBB permeability.
These results are integrative and preclinical: they combine human genomics and experimental validation but do not by themselves establish an effective therapy for people with UC.
Findings combine human genomic analyses and mouse experiments (DSS colitis + ADAM17 inhibitor) and should be considered preliminary regarding therapeutic implications.
