The Mechanism of Pathogenesis of Experimental Autoimmune Uveitis and Possilbilities of Their Regulation
Klímová, Aneta ; Heissigerová, Jarmila (advisor) ; Pitrová, Šárka (referee) ; Holáň, Vladimír (referee)
Introduction:Uveitis in an ocular inflammation affecting mostly people of working age. Uveitis is responsible for severe visual impairment despite of expanding new therapeutics. The animal models of uveitis were established, because the wide clinical variability of uveitis limits the studies in human medicine. The goal our project was to establish a reproducible model of experimental autoimmune uveitis in Czech Republic, and further on this model to observe the frequency of CD3+ and F4/80+ cells in retina, to assess the influence of microbial environment on intensity of intraocular inflammation and to test the therapeutical possibilities. Material and methods: The C57BL/6J mice were immunized by retinal antigen (IRBP 1-20, interphotoreceptor retinoid binding protein), enhanced by complete Freund's adjuvant and pertussis toxin and mild posterior autoimmune uveitis was induced. The mice were bred in conventional and germ-free (gnotobiotic) conditions. The uveitis intensity was evaluated in vivo biomicroscopically and post mortem histologically on hematoxylin eosin stained sections according to the standard protocol. The histological eye specimen were analyzed also by imunohistochemisty and by flow cytometry. Each experiment was performed for 35 days. The conventional mice with uveitis were treated...
