Inflammatory bowel disease (IBD) encompasses a spectrum of gastrointestinal disorders driven by dysregulated immune responses against gut microbiota. We integrated single-cell RNA and antigen receptor sequencing to elucidate key components, cellular states, and clonal relationships of the peripheral and gastrointestinal mucosal immune systems in health and ulcerative colitis (UC). UC was associated with an increase… Continue reading Heterogeneity and clonal relationships of adaptive immune cells in #ulcerative colitis revealed by single-cell analyses

Inflammatory bowel disease is associated with higher dementia risk: a nationwide longitudinal study
Increasing evidence supports reciprocal communication between the enteric and the central nervous system in disease, termed the ‘gut–brain axis’. Recent findings suggest a connection between IBD and development of Parkinson’s disease. The role of IBD in dementia, another insidious neurodegenerative disorder, has not been explored.. ..Overall incidence of dementia among patients with IBD was significantly… Continue reading Inflammatory bowel disease is associated with higher dementia risk: a nationwide longitudinal study
Outcomes of COVID-19 in 79 patients with #IBD in Italy: an IG-IBD study
COVID-19 has rapidly become a major health emergency worldwide. Patients with IBD are at increased risk of infection, especially when they have active disease and are taking immunosuppressive therapy. The characteristics and outcomes of COVID-19 in patients with IBD remain unclear.. ..Between 11 and 29 March 2020, 79 patients with IBD with COVID-19 were enrolled… Continue reading Outcomes of COVID-19 in 79 patients with #IBD in Italy: an IG-IBD study
IFN-γ drives inflammatory bowel disease pathogenesis through VE-cadherin–directed #vascular barrier disruption
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder with rising incidence. Diseased tissues are heavily vascularized ..Specifically, we show that inhibition of the IFN-γ response in vessels by endothelial-specific knockout of IFN-γ receptor 2 ameliorates experimentally induced colitis in mice. IFN-γ acts pathogenic by causing a breakdown of the vascular barrier through disruption of… Continue reading IFN-γ drives inflammatory bowel disease pathogenesis through VE-cadherin–directed #vascular barrier disruption
