    Abstract:
    PURPOSE: To examine the serial expression of cell adhesion molecules in C3H/HeN mice with endotoxin-induced uveitis, and to study the effect of treatment with a monoclonal antibody against Mac-1 on the development of endotoxin-induced uveitis. METHODS: Immunohistochemical staining was used to document the serial expression of Mac-1, intercellular adhesion molecule-1 (ICAM-1), and lymphocyte function-associated antigen-1 (LFA-1) in eyes of C3H/HeN mice with endotoxin-induced uveitis. Then, in two separate experiments, endotoxin-induced uveitis was produced in a total of 48 mice by injecting Salmonella typhimurium endotoxin into one hind footpad. At the time of endotoxin injection, 24 mice received an intraperitoneal injection of anti-Mac-1 antibody and 24 control mice received an intraperitoneal injection of rat IgG. Histopathologic sections of eyes taken 24 hours after endotoxin injection were graded by two masked observers on a scale of 0 to 4. RESULTS: Intercellular adhesion molecule-1 was first expressed on the ciliary body epithelium 6 hr after endotoxin injection and Mac-1 and LFA-1 were expressed on infiltrating inflammatory cells 12 hr after endotoxin injection. Treatment with anti-MAC-1 antibody significantly inhibited the development of ocular inflammation when compared with treatment with control IgG (P < 0.001). CONCLUSION: Intercellular adhesion molecule-1 is expressed in the eye before clinical or histologic signs of inflammation. Furthermore, treatment with antibody against Mac-1 significantly inhibits the development of endotoxin-induced uveitis in mice and suggests that anti-Mac-1 antibody may be useful for treating acute ocular inflammation.
