Michelsen Lab
Inflammatory bowel diseases (IBD) are characterized by chronic or recurring inflammation of the gastrointestinal tract. IBD is thought to result from an overactive and continuous immune response to intestinal microbiota, including commensal and pathogenic bacteria, in a genetically susceptible host. IBD affects an estimated 1.4 million Americans. The Michelsen Laboratory is studying the underlying mechanisms that lead to the development of chronic inflammatory diseases such as IBD and colon cancer.
The Michelsen Laboratory is affiliated with the Cedars-Sinai F. Widjaja Foundation Inflammatory Bowel and Immunobiology Research Institute, the Department of Medicine and the Department of Biomedical Sciences.

She is also an adjunct associate professor at the University of California, Los Angeles, David Geffen School of Medicine.
Kathrin Michelsen, PhD

The Michelsen Laboratory is particularly interested in the role of the innate immune system in the development of inflammatory bowel diseases (IBD). Recent reports have shown that genetic variations in the gene encoding for a tumor necrosis factor family member called tumor necrosis factor-like cytokine 1A (TL1A) confer susceptibility to IBD.
