Our previous studies have demonstrated that lens epithelial damage by excessive nitric oxide causes an elevation in lens opacification in UPL rats, and it has been reported that interferon-gamma production in lens epithelial cells is involved in cataract development. In this study, we investigated the involvement of interleukin (IL)-18, which leads to interferon-gamma, in UPL rat lenses. The opacification of UPL rat lenses starts at 39 days of age. The gene expression levels causing IL-18 activation (IL-18, IL-18 receptor and caspase-1) are increased at 32 days of age, and the expression of mature IL-18 protein in the UPL rat lenses also increases with ageing. On the other hand, the interferon-gamma levels in UPL rat lenses are increased, and the increase in interferon-gamma levels in UPL rat lenses reaches a maximum at 39 days of age. Mature IL-18 expression and interferon-gamma production are achieved prior to the onset of lens opacification. In conclusion, the expression levels of IL-18 in the lenses of UPL rats are increased with aging. In addition, interferon-gamma levels in the lenses of UPL rats are also increased. It is possible that interferon-gamma generated by the activated IL-18 may induce cataract development in UPL rats.
