    NF-κB activation by IL-1β is not functional in ΔMYD88 clones. (A) A Western blot for phospho-NF-κB and the IRAK pathway proteins IRAK1, IRAK4 and MYD88 in WT and ΔMYD88 BCBL-1Cas9 cells 15 min post IL-1β stimulation (1 ng/μl IL-1β).

Two ΔMYD88 clones and WT BCBL-1Cas9 cells were stimulated with 1 ng/μl IL-1β, or mock PBS for 24 h h following transfection, and luciferase values measured 6 h h post stimulation. Results are fold change over mock. (C) Two ΔMYD88 clones and WT BCBL-1Cas9 cells were stimulated with TNF-α (1 ng/ml), and the response was compared to mock using the same procedure as in panel B.

    Comparison of in vitro and in culture IRAK inhibitor activity. (A) EC50 curves (growth) for three commercially available IRAK inhibitors. Fraction of response is shown on the vertical axis and concentration (in μM) on the horizontal axis. Inh1 (CAS no. 1042224-63-4), Inh4 (CAS no. 1012104-68-5), and Inh1-4 (CAS no. 509093-47-4). The EC50 value on each plot is the average from four experiments. (B) Quantification of luciferase production in cells transfected with an NF-κB-driven luciferase plasmid, incubated with inhibitor, a nd stimulated with 1 ng/μl IL-1β. Luciferase values were measured 6 h poststimulation. All values are fold change over that with mock PBS stimulation on the vertical axis and inhibitor concentration (in μM) on the horizontal axis. (C) A DiscoverX KINOMEscan analysis for each IRAK inhibitor at 250 nM. Purple or blue dots and represent IRAK4 or IRAK1 kinase, respectively. Size of the circle is proportional to percent activity inhibited by the inhibitors.
