The Neuromodulation of the Intestinal Immune System and Its Relevance in Inflammatory Bowel Disease KU Leuven
One of the main tasks of the immune system is to discriminate and appropriately react to "danger" or "non-danger" signals. This is crucial in the gastrointestinal tract, where the immune system is confronted with a myriad of food antigens and symbiotic microflora that are in constant contact with the mucosa, in addition to any potential pathogens. This large number of antigens and commensal microflora, which are essential for providing vital ...
Absence of intestinal inflammation and postoperative ileus in a mouse model of laparoscopic surgery KU Leuven
Postoperative ileus (POI) is characterized by impaired gastrointestinal motility resulting from intestinal handling-associated inflammation. The introduction of laparoscopic surgery has dramatically reduced the duration of POI. However, it remains unclear to what extent this results in a reduction of intestinal inflammation. The aim of the present study is to compare the degree of intestinal inflammation and gastrointestinal transit following ...
Mast cells play no role in the pathogenesis of postoperative ileus induced by intestinal manipulation KU Leuven
Intestinal manipulation (IM) during abdominal surgery results in intestinal inflammation leading to hypomotility or ileus. Mast cell activation is thought to play a crucial role in the pathophysiology of postoperative ileus (POI). However, this conclusion was mainly drawn using mast cell-deficient mouse models with abnormal Kit signaling. These mice also lack interstitial cells of Cajal (ICC) resulting in aberrant gastrointestinal motility even ...
Spleen Tyrosine Kinase Inhibition Reduces Intestinal Inflammation and Prevents Postoperative Ileus KU Leuven
Spatially resolved transcriptomic profiling of degraded and challenging fresh frozen samples KU Leuven
Spatially resolved transcriptomics has enabled precise genome-wide mRNA expression profiling within tissue sections. The performance of methods targeting the polyA tails of mRNA relies on the availability of specimens with high RNA quality. Moreover, the high cost of currently available spatial resolved transcriptomics assays requires a careful sample screening process to increase the chance of obtaining high-quality data. Indeed, the upfront ...
