H&E staining, SEM, and VG staining showed that Garidisan repaired damaged intestinal mucosa and significantly reduced expression of ICAM-1 and CD105 in regenerated tissues of UC rats.
This meta-analysis demonstrates that the ICAM-1K469E polymorphism may be associated with susceptibility to CD in Europeans, but no association was found between ICAM-1K469E and UC.
Although such interactions may aid in clearance of invading microorganisms by promoting PMN recruitment, engagement of ICAM-1 under pathologic conditions would increase accumulation of epithelial-associated PMN, thus contributing to mucosal injury as observed in conditions, including ulcerative colitis.
We found an increase in the levels of inflammatory markers from serum (tumor necrosis factor-α, IL-1β, IL-6 and the acute phase protein C-reactive protein) and substantia nigra (tumor necrosis factor-α, IL-1β, IL-6, inducible nitric oxide synthase, intercellular adhesion molecule-1, microglial and astroglial populations) of rats with UC, as well as an alteration of the blood-brain barrier permeability and the loss of dopaminergic neurons.
The aim of this study was to assess the ICAM-1 expression in human colonic tissue representing UC, Crohn's disease (CD), adenomas, and adenocarcinomas, with special attention to the epithelium.
These findings suggest that the polymorphisms observed in the NOD2/CARD15, NOD1/CARD4, and ICAM-1 genes are not genetic susceptibility factors for Crohn's disease or ulcerative colitis in Turkey.
Increased adhesiveness of circulating leukocytes seems to be involved in the pathogenesis of UC, and ICAM-1 is suggested to be a part of this phenomenon.
The results showed that NF-kappaB DNA binding activity, mRNA and protein expression of ICAM-1 and VCAM-1 were increased significantly in patients with UC, compared with normal control (P<0.05).
Two candidate genes (DDXL and ICAM-1) within the IBD6 locus were examined in a case/control study with a total of 228 CD and 243 ulcerative colitis (UC) patients and 407 healthy controls.
Ulcerative colitis and Crohn's disease are associated with polymorphisms of the ICAM-1 gene, which might therefore represent a functional candidate gene.
Because the codon 241 polymorphism is in a functionally important domain III of ICAM-1, we may have identified an actual responsible genetic variation for genetically heterogeneous subsets of both UC and CD.
