title: Down-regulation of adhesion molecules and matrix metalloproteinases by ZK 156979 in inflammatory bowel diseases.
abstract: Intracellular adhesion molecules and matrix metalloproteinases (MMPs) are up-regulated in intestinal mucosa of patients with inflammatory bowel diseases (IBD), i.e. ulcerative colitis (UC) or Crohn's disease (CD). Our aim was to verify whether the vitamin D analogue ZK 156979 (ZK) down-regulates adhesion molecules, and decreases MMPs production by PBMC of IBD patients. ICAM-1 and LFA-1 levels increase, when PBMC were incubated with PHA or LPS or TNF-alpha, and decrease when these substances were used in combination with ZK. MMPs activity increases incubating the cells with PHA or LPS or TNF-alpha. MMP-9 decreases when ZK was used in association, while MMP-2 decreases only when ZK was used in combination with anti-TNF-alpha. Our results suggest that the down-regulation of ICAM-1 and LFA-1 on PBMC and the inhibition of MMP-9 activity by ZK could provide a potential role of this low calcemic vitamin D derivative in future strategies in IBD therapy.
