Our bodies are constantly exposed to a multitude of challenges, such as microbes, toxins, and injuries, especially at barrier surfaces like the skin, lungs, and intestines. These tissues serve vital and complex functions in shielding us from environmental threats while also managing body moisture, oxygen levels, and nutrient absorption. For instance, the intestine must delicately balance the elimination of harmful microbes and toxins with the absorption of essential nutrients. This requires intricate cooperation between the intestinal lining cells and the intestinal immune system. Barrier tissues, like the intestine, are particularly prone to inflammation and cancer.
Inflammatory bowel diseases are chronic inflammatory conditions affecting the intestines. They result from an interplay of genetic and environmental factors, leading to dysregulated functioning of intestinal cells and immune system. These incurable diseases can significantly increase the risk of developing colon and rectal cancer. Yet, the mechanisms through which environmental factors and inflammation impact the immune system and cells of the intestine to drive the progression of chronic inflammatory diseases and cancer remain largely unknown.
Within the Niec lab, innovative tools have been developed to investigate how immune cells and the intestinal barrier cells respond to environmental challenges and interact in disease. Through this project, we aim to unravel the alterations occurring in the immune system and the intestine during inflammation. By understanding these processes, we aspire to develop strategies to prevent and treat cancer that arises from inflammatory bowel disease.
