Time kinetics of IRAK phosphorylation induced by different agonists.
Medium alone (Ctr), IL-1β (1 U/mL), polyclonal anti–β2-GPI IgG (IgG Pos; 200 μg/mL), NHS IgG (IgG Neg; 200 μg/mL), and LPS (10 ng/mL) were used. To evidence equal loading of the lanes, in control experiments one tenth of each supernatant after IRAK immunoprecipitation was run on an SDS-PAGE gel and blotted against β-actin (lower panel).
