MyD88-/- mice have decreased levels of cytokines in the conjunctiva.

IL-1α (A), IL-6 (B), IL-2 (C), and IL-9 (D) expression were determined in untreated conjunctival homogenates from wild-type (WT), IL-1R-/-, and MyD88-/- mice by Luminex multiplex assay. Data represent mean ± SEM of 3 independent experiments with each sample pooled from 5 mice. Analysis was performed by ANOVA with Bonferroni’s test for multiple comparisons, with comparison to WT samples. p<*0.05, **0.01.
