(2008): Tyk2 and signal transducer and activator of transcription 1 contribute to intestinal I/R injury.

Abstract:
Previously, we have shown that the Jak-signal transducer and activator of transcription signaling constituents Tyk2 and STAT1 play a role in the development of multiple organ failure during endotoxin shock. Here, we report that Tyk2 and STAT1 contribute to death caused by intestinal I/R injury. Tyk2- and STAT1 -deficient mice showed increased survival to I/R because their intestines were protected from gross histomorphological tissue destruction and neutrophil infiltration. On the molecular level, the reduced ischemia induced inflammatory response in mutant versus wildtype mice was accompanied by an impaired up-regulation of the adhesion molecules P-selectin and intercellular adhesion molecule 1 and of the matrix metalloproteinases (MMPs) MMP-2, MMP-9, and MMP-14 in the reperfused intestine. In conclusion, this study demonstrates for the first time that Tyk2 or STAT1 promote intestinal I/R-induced shock based on a deregulated local inflammatory response and a destruction of the gut intestinal barrier.
