Most genetic variants associated with complex diseases lie in non-coding regions<sup>1</sup>, complicating efforts to identify effector genes and relevant cell types. Here we map cis-expression quantitative trait loci (eQTLs) across 2.2 million single cells using intestinal biop…

Single-cell analysis of Crohn’s disease lesions identifies a pathogenic cellular module associated with resistance to anti-TNF therapy
Clinical benefits of cytokine blockade in ileal Crohn's disease (iCD) are limited to a subset of patients. Here, we applied single-cell technologies to iCD lesions to address whether cellular heterogeneity contributes to treatment resistance. We found that a subset of patients e…

IPF Cell Atlas
We provide a single-cell atlas of idiopathic pulmonary fibrosis (IPF), a fatal interstitial lung disease, by profiling 312,928 cells from 32 IPF, 28 smoker and nonsmoker controls, and 18 chronic obstructive pulmonary disease (COPD) lungs. Among epithelial cells enriched in IPF, …

Human CD atlas study between colon and terminal ileum
Crohn's disease (CD) is a chronic gastrointestinal disease that is increasing in prevalence worldwide. CD is multifactorial, involving the complex interplay of genetic, immune, and environmental factors, necessitating a system-level understanding of its etiology. To characterize…

Reveal the key mediators of inflammation in Crohn's disease undergoing biological treatments
Total proctocolectomy with ileal pouch anal anastomosis is the standard of care for patients with severe ulcerative colitis. We generated a cell-type-resolved transcriptional and epigenetic atlas of ileal pouches using scRNA-seq and scATAC-seq data from paired biopsy samples of …

An immune-cell signature of bacterial sepsis (Patient PBMCs)
Inflammatory bowel disease (IBD) and Sepsis are both characterised by immune dysregulation. Notably, IBD is a factor in the increase in septic infections. However, these two conditions' shared molecular and pathophysiological mechanisms remain unclear. We used 'limma' and 'WGCNA…

TL1A-activated Tcells as upstream regulators of perianal fistulizing disease-associated changes in the rectum of Crohn's Disease patients [scRNA-seq]
<h4>Background</h4>Perianal fistulising disease (PFD) is a complication that affects about 20% of patients with Crohn's disease (CD) whose aetiology remains unknown.<h4>Objectives</h4>To identify predisposing events driving fistula formation.<h4>Design</h4>Rectal biopsies from p…
