AAV8-HLA-G1/5 Improves EAU histology scores. (a) Representative images of ocular histology demonstrate iris thickening and severe inflammatory cell infiltration in the ciliary body, iris, anterior chamber and vitreous body, as well as moderate vasculitis formation in experimental autoimmune uveitis (EAU) untreated eyes (C,D). Mild infiltration of inflammatory cells was observed in the vitreous and retina in topical dexamethasone and HLA-G1/5 treated EAU eyes (E&F, G&H, respectively). Control healthy eyes (A&B). (hematoxylin & eosin staining, original magnification: 20x and 40x). The histological infiltrative scores (b) and structural scores (c) were significantly decreased in the scAAV8-HLA-G1/5 treated (n = 4 eyes) and dexamethasone (dex) treated EAU eyes (n = 4 eyes) as compared to the non-treated EAU eyes (n = 4 eyes) (p = 0.01, p = 0.02; Wilcoxon test). There was no significant difference between healthy eyes (n = 2 eyes) and either EAU treatment group. Each point is the average score of an individual eye of two blinded observers and mean scores of each treatment group are denoted by the horizontal bars.
