11. Impact of genetic and environmental factors in intestinal inflammation
Sammanfattning : The gastrointestinal tract, is continuously exposed to a wide variety of stimuli, including dietary-derived metabolites, environmental compounds and the microbiota. Since these antigens can be beneficial or detrimental for the organism, proper sensing of the luminal content is essential for orchestrating both pro-inflammatory and tolerogenic immune responses on demand and therefore, ensure the establishment of intestinal homeostasis.

12. Intestinal ischemia and reperfusion. Proinflammatory response and organ dysfunction
Sammanfattning : Intestinal I/R is considered to be an important initiating event in several pathophysiological conditions such as trauma, bleeding, sepsis and pancreatitis, frequently leading to concomitant both single and potentially multiple organ dysfunction. The purpose of this thesis was to study mechanims underlying the development of multiple organ dysfunction, with special focus on intercellular proinflammatory regulation in the concurrent development of tissue injury.

13. Inflammation and Intestinal Homeostasis-Associated Genes in Colorectal Cancer
Sammanfattning : Colorectal cancer (CRC) is a global ‘killer’ and every year more than 1.2 million new individuals are affected and approximately 600 000 succumb to the disorder. Several mechanisms such as inactivation of tumor suppressor genes, activation of oncogenes and dysregulation of cell fate determinating pathways e.g. LÄS MER
14. Platelet-activating factor, intestinal epithelial cells, and Chron's disease : An experimental study
Sammanfattning : Platelet-activating factor (PAF-acethcr, 1-0-alky l-2-acetyl-s n- glycero-3- phosphocholine), is a potent inflammatory mediator that can be formed by a variety of cells and tissues. In the present investigation, the content of PAFacether was determined in mucosal biopsies from the ileum and colon of patients with Crohn's disease and control patients. LÄS MER
15. Innate lymphoid cells and cholesterol metabolism in intestinal barrier function
Sammanfattning : The intestinal mucosa represents one of the largest barrier sites of our body, having to withstand a constant exposure to a plethora of environmental insults (including dietary compounds, xenobiotics, metabolites and microorganisms). While our body has evolved tolerance/ignorance towards some of these factors deemed beneficial for the host, it requires constant maintenance of epithelial barrier integrity and ability to mount pro-inflammatory responses to protect against potentially harmful environmental insults.
