| Outline of Final Research Achievements |
In this study, mechanism that excess amount of nitric oxide (NO) produced in ulcerative colitis is involved in the inflammation of colonic mucosa was investigated using the magnetic resonance technique. The scheme was proposed as follows; 1) NO produced from activated macrophages infiltrating into the colonic tissue would trigger the activation of TLR4-NF-kB pathway, which was brought by the CD14 expression enhanced by STAT3 activation. 2) The increase of IL-6 level induced by the activated NF-kB would lead to the further activation of STAT3. 3) The increase of expression of adhesion molecules induced by the activated NF-kB would cause the infiltration of neutrophils producing reactive oxygen species leading to the mucosal injury.
