Project description:Analysis of neutrophil proteomic alterations induced by migration towards inflamed joints in juvenile idiopathic arthritis (JIA). In this experiment neutrophil proteomes were investigated after migration towards JIA synovial fluid in an in vitro model of a synovial membrane, compared to neutrophils incubated in synovial fluid without migration. The migration model consisted of transwell inserts with human knee synoviocytes on the undersides and HMEC endothelial cells on the insides, placed in wells containing medium with 10 % JIA synovial fluid.
Project description:Patient-derived intestinal organoids provide an excellent tool to unravel mechanisms underlying ulcerative colitis (UC). Fresh biopsies, to isolate crypts and culture organoids, were obtained from both inflamed and non-inflamed regions from eight patients with active UC (Mayo endoscopic subscore ≥2), and from eight non-IBD controls.To address the inflammatory character of ex vivo organoids, we compared the transcriptome of biopsies, crypts and organoids derived from inflamed, and non-inflamed regions and aimed to (re-)induce inflammation ex vivo.
Project description:biopsies from the most inflamed area were sequenced where applicable. FACS-sorted cell populations: N=neutrophils; M=mononuclear phagocytes; S=stromal cells; E=eosinophils
Project description:To investigate the gene expression profile of inflamed and non-inflamed mucosa in patients with Crohn's disease. To investigate TCR repertoires in the intestinal mucosa, the expression profile of the TCR repertoire gene was analyzed.
Project description:Dataset containing single-cell RNA sequencing data of >17,000 healthy and perturbed murine neutrophils across biological tissues. This study contains expression data from healthy tissues (bone marrow, spleen, peripheral blood) as well as models of experimental (K/BxN serum transfer arthritis: peripheral blood and joint, IL-1β peritonitis and IL-1β pneumonitis). Single cell RNA-sequencing was performed on the 10X platform
