Uveitis is an inflammatory disease associated with diverse systemic and autoimmune diseases, defined as the inflammation of any given segment of the uveal tract, uveitis contributes with 5-20% cases of blindness in the USA/Europe and >25% of cases in third-world countries. To understand its pathogenic mechanisms, BALB/c and C57BL/6 mice were induced to develop the condition by a single intraperitoneal injection of E. coli lipopolysaccharide, the aim of the present work is to determine leukocyte infiltration in an endotoxin-induced uveitis (EIU) in two non-related mouse strains. Histopathological findings and clinical analysis were conducted 24 and 48 h postinjection. Both strains presented conventional clinical signs of uveitis 24 h post LPS injection and the highest inflammatory leukocyte infiltration in the uveal tract was found in the BALB/c mouse strain. This article will give an insight on the difference of the inflammatory response in the EIU model in two different mouse strains and the relationship between the pathologic response.
