The study supports the findings of the recent NF-kB research given that infliximab neutralizes an inflammation-causing protein called tumor necrosis factor alpha. This protein regulates "a common inflammation pathway that just happens to be important in Crohn's disease," suggesting that a specific, targeted molecular approach to treatment may be more helpful for Crohn's patients than steroids (Seppa 2008)
Future drugs, however, could directly address the problems regarding NF-kB, rather than simply treating the symptoms of inflammation. "NF-kB acts as a survival signal for cells. Without the molecule cells are much more likely to die and this is what happened in the intestines of... [the] mice; individual epithelial cells died disrupting the gut lining. Through these gaps bacteria could penetrate the intestinal wall. Right behind the gut epithelium lie cells of the intestinal immune system, the biggest immune system of our body. It detects the invading bacteria and generates a strong immune response to fight off the invaders. In the process of combating the bacteria, the immune cells secrete a cocktail of signals that bring about the symptoms of inflammation...Inflammatory signals also reach the epithelial cells that due to the lack of NF-kB are very sensitive to them and die. The death of more epithelial cells creates bigger gaps in the gut lining so that more bacteria enter. The result is a constant immune response leading to chronic inflammation" ("Researchers Identify Molecular Basis of Inflammatory Bowel Disease," 2007, European Molecular Biology).

Inflammatory Bowel Disease: Immunological, Demographical, and Genetic Findings Inflammatory bowel disease (IBD) affects the colon and the small intestine. Though there are many subtypes of IBD, the most common and well-known are Crowns disease and ulcerative colitis (WebMD.com, 2011). Crohn's disease causes symptoms such as abdominal pains, diarrhea, vomit, weight loss, as well as many non-digestive system related pains (WebMD.com, 2011). Ulcerative colitis is quite similar to Crohn's disease due to noticeable
According to these authors, the fatal tragedy could easily have been avoided by taking more time for more focused and carefully planned clinical trials. According to this view, it was unethical to test Tysabri in the way it has been done, and furthermore irresponsible to enter it into the market before all side-effects were ascertained. 3. Interested parties: The interested parties in this case include Walter Smith, Anita's widower, as
