Fig. 4: NOD2 signalling.

Patient and control (n = 5) peripheral blood was stimulated with MDP (10 µg/ml) for 20 min, and phosphorylation of a MAP kinases were detected by phospho-flow cytometry b and by Western blot. NFκB signalling, expressed as IκB degradation and NFκB phosphorylation, was detected by c flow cytometry and d by Western blot after MDP (10 µg/ml) stimulation of patient and control (n = 5) peripheral blood cells. e Production of IL-1β, TNFα, IL-6 and IL-12p70 after MDP (10 µg/ml) or LPS (1 µg/ml) stimulation of patient and control (n = 5) PBMCs was detected by Luminex.
