The inhibitory mechanism of interferon-gamma (IFN-gamma) on the fibroblasts from Tenon's capsule was studied. By using immunohistochemical SP method and pathological image system, the inhibitory effects of IFN-gamma on the expression of transforming growth factor beta receptor I in the in vitro cultured fibroblasts from Tenon's capsule were quantitatively analyzed. The results showed that IFN-gamma could reduce the expression of transforming growth factor beta receptor I in the fibroblasts with the following dose-effect relationship: Y = 1937.5-134.2 Igx (r=-0.971, P<0.01). It was concluded that IFN-gamma could inhibit the expression of transforming growth factor beta receptor I in the fibroblasts from Tenon's capsule. The modulation of the transforming growth factor beta receptor I expression by IFN-gamma may be beneficial to the alleviation of the hyperplasia of scar after trabeculectomy.
Ocular allergy includes several clinical subtypes ranging from the mild seasonal allergic conjunctivitis to the potentially sight-threatening atopic keratoconjunctivitis. Current therapies, particularly for the severe forms of disease, need to be more localized and with fewer side effects. For this to be achieved, it requires a better understanding of the basic mechanisms involved. In this chapter, recent findings are discussed that suggest that it is important to take an integrated approach, including both immune and structural elements of the eye. This provides potential new strategies for therapy, addressing the influence of structural cells in disease. These might influence the immune processes that take place and, as the structural cells are precisely localized, topical application is likely to be effective.
