- PURPOSE. Aged C57BL/6J (B6) mice have increased levels of cathepsin S, and aged cathepsin S (Ctss−/−) knockout mice are resistant to age-related dry eye. This study investigated the effects of cathepsin S inhibition on age-related dry eye disease. METHODS. Female B6 mice aged 15.5 to 17 months were randomized to receive a medicated diet formulated by mixing the RO5461111 cathepsin S inhibitor or a standard diet for at least 12 weeks. Cornea mechanosensitivity was measured with a Cochet–Bonnet esthesiometer. Ocular draining lymph nodes and lacrimal glands (LGs) were excised and prepared for histology or assayed by flow cytometry to quantify infiltrating immune cells. The inflammatory foci (>50 cells) were counted under a 10× microscope lens and quantified using the focus score. Goblet cell density was investigated in periodic acid–Schiff stained sections. Ctss−/− mice were compared to age-matched wild-type mice. RESULTS. Aged mice subjected to cathepsin S inhibition or Ctss−/− mice showed improved conjunctival goblet cell density and cornea mechanosensitivity. There was no change in total LG focus score in the diet or Ctss−/− mice, but there was a lower frequency of CD4+IFN-γ+ cell infiltration in the LGs. Furthermore, aged Ctss−/− LGs had an increase in T central memory, higher numbers of CD19+B220−, and fewer CD19+B220+ cells than wild-type LGs. CONCLUSIONS. Our results indicate that therapies aimed at decreasing cathepsin S can ameliorate age-related dry eye disease with a highly beneficial impact on the ocular surface. Further studies are needed to investigate the role of cathepsin S during aging.
