Open Targets @opentargets.org · 12/08/2026After persuading funding bodies—Open Targets, the @sangerinstitute.bsky.social, and the Crohn’s and Colitis Foundation—that this was worth the gamble, they launched the “IBDverse”, and processed almost 1200 samples from over 600 patients. Nothing on this scale had ever been attempted before. 110
Open Targets @opentargets.org · 12/08/2026Ambitious science can start in the most unglamorous places. In 2015, gastroenterologist Tim Raine and geneticist Carl Anderson had a casual conversation in an underground carpark, which led to the largest single-cell dataset of Inflammatory Bowel Disease (IBD)-relevant tissues 172
Open Targets @opentargets.org · 04/08/2026We talked to Menatallah Ghouraba, Rebecca McIntyre, and Cristina Cotobal Martin to get a behind-the-scenes perspective on the project.

Open Targets @opentargets.org · 15/06/2026In particular, they found an upregulation of MHC-I driven by interferon, which persists in progenitor cells after visible inflammation heals.

Open Targets @opentargets.org · 03/06/2026These findings help resolve the biology of IBD, and nominate targets for drug development or repurposing. A similar approach could be applied to other complex diseases to nominate effector genes from GWAS loci. 100
Open Targets @opentargets.org · 03/06/2026By mapping eQTLs at three progressively higher resolutions, they found over 84,000 eQTLs in 251 cellular annotations. Notably, many eQTLs were only found at higher resolutions, and cell-type-level eQTLs were more than twice as likely to colocalise with IBD GWAS loci than tissue-level eQTLs. 110
Open Targets @opentargets.org · 03/06/2026To test this hypothesis, they generated the largest collection of single-cell RNA sequencing data from IBD-relevant sites (terminal ileum, rectum, blood), resulting in nearly 2.2 million single-cell transcriptomes from over 400 individuals including 125 with IBD. 100
Open Targets @opentargets.org · 03/06/2026@tobioinformatics.bsky.social @bradleyomics.bsky.social hypothesised that colocalising GWAS signals with cell-type-specific single-cell eQTLs would more readily nominate disease effector genes, since regulators active only in specific cellular contexts are more likely to escape purifying selection 100
Open Targets @opentargets.org · 03/06/2026Genetics are a good starting point for drug development, but while Genome Wide Association Studies have nominated loci for IBD, only a fraction of these have successfully been linked to causal genes with current eQTL discovery methods, which often rely on bulk RNA sequencing of heterogeneous tissues 100
