APC0576 decreases production of pro-inflammatory chemokine and extracellular matrix by human Tenon's capsule fibroblasts.

PURPOSE: To control intraocular pressure in patients treated by trabeculectomy, progressive inflammation, fibroblast proliferation, and the enhanced expression of extracellular matrix ( ECM), causes of scar formation at the bleb, must be prevented. Using human Tenon's capsule fibroblasts (TCFs), we examined the effect of APC0576, a suppressor of NF-kappaB-dependent gene activation of human vascular endothelial cells that does not adversely affect cell viability, on the production of pro-inflammatory chemokine and ECM. Its effect on TCF proliferation was also assessed. METHODS: Enzyme-linked immunosorbent assay was used to detect the pro-inflammatory cytokines IL-8 and MCP-1 in the supernatant of TCFs stimulated with IL-1alpha in the presence or absence of APCO576 and ECM proteins, COOH-terminal peptide of type I procollagen (PIP), fibronectin (FN), and laminin (LN) in supernatants and lysates of TCFs stimulated with IL-1alpha or TGF-beta. The proliferative response of IL-1alpha-stimulated TCFs was examined using the SF formazan solution reaction. RESULTS: APC0576 significantly suppressed the production by TCFs of IL-8 (p<0.0001), MCP-1(p<0.0001), PIP (supernatants: p<0.0001, cell lysates: p<0.0001), LN (supernatants: p<0.0001, lysates: p<0.0001), and FN (supernatants: p<0.0001, lysates: p<0.0001) as well as their proliferation (p<0.0001). CONCLUSIONS: APC0576 suppressed pro-inflammatory chemokine and ECM production in TCFs as well as their proliferation. It may represent a novel candidate for the postoperative management of patients treated by trabeculectomy.[1]
