SLAMF1 silencing in macrophages impairs TLR4-mediated phosphorylation of TBK1, IRF3, and TAK1. Western blotting of lysate macrophages treated with a control nonsilencing oligonucleotide or SLAMF1-specific siRNA oligonucleotides and stimulated with 100 ng/ml LPS. The antibodies used are indicated in the figure. An antibody toward SLAMF1 was used to control for SLAMF1 silencing, and GAPDH was used as an equal loading control. Same GAPDH controls are presented for pTBK1, total TBK1, and phospho-p38MAPK, for total IRF3 and total TAK1, and for pTAK1 and pIκBα because they were probed on the same membranes. Western blots are representative of one of five donors. Molecular weight is given in kilodaltons. Graphs (right) show quantifications of protein levels relative to GAPDH levels obtained with Odyssey software.
