Investigation of cytokines involved in inflammatory processes leading to digestive diseases is the goal of research now being conducted by Dr. Claudio Fiocchi, professor of medicine and head of gastroenterology research, Case Western Reserve University, Cleveland, Ohio.
In his state-of-the-art lecture, Dr. Fiocchi will discuss how cytokines alter the behavior of cells, producing either a greater-than-normal inflammatory response or enhancing intrinsic anti-inflammatory responses as well."Cytokines are key mediators of inflammation in general, and this is also true for inflammation in the gastrointestinal tract in diseases such as Crohn's disease, ulcerative colitis and celiac disease," said Dr. Fiocchi in an earlier interview.
Understanding the type, amount and timing of the cytokines being released is important, he added, initially because it will help determine the pathophysiology of certain inflammatory responses in the gut.
Later on, a better understanding of how inflammation develops opens up potential avenues through which pathological responses may be controlled through either modulation, inhibition or augmentation of specific cytokine production.By blocking certain cytokines, for example, processes which would normally augment the inflammatory response could be down-regulated and inflammation subsequently repressed.
Conversely, manipulation of cytokines which mediate anti-inflammatory responses could help suppress inflammation and symptoms of diseases, such as ulcerative colitis and Crohn's disease, in which inflammation plays a fundamental pathogenic role.Research in this area is already paying off, as Dr. Fiocchi noted.
For example, anti-tumor necrosis factor antibodies are currently being used to treat Crohn's disease to block events which promote inflammation.Treatment with interleukin-10 and interleukin-11, on the other hand, supplies anti-inflammatory cytokines which in turn dampen down inflammation.
"Cytokines have multiple actions but one of the hopes is that we can find a way of modulating the predominant function of specific cytokines so that we can treat inflammation by attacking a more specific therapeutic target," said Dr. Fiocchi.Dr. Fiocchi will give his state-of-the-art lecture on Tuesday, August 31st at 8:00 to 8:45 am in meeting rooms 10, 11 & 12 of the Convention Centre.
