Figure 2. ORLL-NIH001 conferred protection from development of severe EAU.

Figure 2

(A) Schematic depiction of immunization protocols used for EAU induction in B10.A mice. Mice treated under Protocol 1 received injections of ORLL-NIH001, starting 1 day before immunization (day −1) and on every other day thereafter until day-17 post-immunization. Protocol 2: mice began receiving the drug on day-5 post-immunization. Mouse eyes were harvested, fixed, embedded in paraffin and stained with H&E. (B, D) Histological analysis showing: inflammatory cells in the vitreous (black arrows), retinal folds (white arrows). OpN, optic nerve; V, vitreous; GCL, ganglion cell layer; INL, inner nuclear layer; ONL, outer nuclear layer. (C, E) EAU scores were calculated for vehicle-treated (control) or ORLL-NIH001-treated mice based on and histology. Similar results were obtained in mice treated under Protocol 1 (B, C) or Protocol 2 (D, E) and data presented are representative of at least 3 independent experiments.
