Figure 3. PI3K p110δD910A/D910A macrophages demonstrate heightened sensitivity to TLR stimulation.

BMMs from WT (black bars) and PI3K p110δD910A/D910A (grey bars) mice were stimulated with TLR9 (CpG), TLR2 (sBLP) or TLR5 (Flagellin) ligands for 24 hours. Supernatants were analyzed for IL-12 p40, IL-12 p70 or IL-23 secretion by ELISA and nitric oxide secretion by Greiss reaction. Error bars represent mean+SEM of 3 independent experiments.
