Figure Lengend Snippet: (A-C, E-G, I) Kdo-2 Lipid A and P3C co-treatment (50 nM each) in iBMDMs. (D, H) Co-TLR (PAMP: Kdo-2 Lipid A and P3C, 50 nM each) or multi-PRR priming (heat-killed Yersinia pseudotuberculosis , MOI 100) followed by Nigericin (10 μ M) trigger for 2h. (A) Quantification of the Pearson’s correlation coefficient (PCC) for the correlation of pJNK antibody staining in IRAK1 clusters. (B) Quantification of the Mander’s colocalization coefficient (MCC) for the co-occurrence of pJNK antibody staining in IRAK1 clusters. (C) pJNK staining in Irak1 −/− iBMDMs. (D) IRAK1-pJNK PLA. (E) PCC and (F) MCC for pMKK7 antibody staining in IRAK1 clusters. (G) pMKK7 staining in Irak1 −/− iBMDMs. (H) IRAK1-pMKK7 PLA in BMDMs. (I) pMKK4 staining in iBMDMs mIRAK1mCherry. (Panels A, B, E, F) Each data point represents value from a randomly selected non-over lapping field of cells. Paired t test. Data are represented as mean ± SD. Automated imaging of at least 2 (Panels C, G, I) fields of cells. At least 20000 (Panels D, H) cells imaged. p = 0.1234 (ns), 0.0332(*); 0.0021 (**); 0.0002 (***); < 0.0001 (****). Data shown are representative of at least two independent experiments.
