EphB2 expression on BMDCs can be modulated by ligation with Toll-like receptor ligands.

<p>(A) BMDC were incubated with a Toll Like receptor (TLR)-4 agonist (lipopolysaccharide (LPS) 1μg/ml) and (B) a TLR-9 agonist (CpG1668 1μM) with or without recombinant mouse interferon (IFN)-γ at a concentration of 20ng/ml. <i>EphB2</i> mRNA was quantified by qPCR at different time points post-stimulation. The modulation of transcription for known co-stimulatory molecules CD80 and CD86 as well as the cytokine interleukin (IL)-12p40 in response to TLR stimulation in the same experiments are shown for comparison. (C) The change in EphB2 protein expression at 22 hours post-incubation with LPS and IFN-γ is shown and the mean fluorescence quantified for different conditions. All graphs represent the median value of pooled data across 3 independent BMDC preparations ±SD and data analyzed using One-way ANOVA– Kruskal Wallis test and Dunn’s multiple comparisons post-test. *P<0.05.
