IL1B and posterior uveitis: Likewise, a significant upregulation of IL1β, IL6, and CD11b (IL1β- PU vs. control, FC-4.4 ± 0.6; *p = 0.01; IL6- PU vs. control, FC-6.8 ± 1.2; *p = 0.04; CD11b- PU vs. control, FC-14.8 ± 1.3; *p = 0.02) was observed in the posterior uveitis category, while IL4 was downregulated (PU vs. control, FC -2.8 ± 0.9; p = 0.3).
