Macrophage exposures RAW264.7 cells were seeded into 24-well plates (200,000 cells/well). The next day, the medium was replaced with medium containing the indicated doses of either E. coli O111:B4 LPS (List Biological Labs), PAM3CSK4 (Invivogen), or poly(I:C) (Invivogen). Following the exposure, cells were lysed in RLT for RNA preparation. Additionally, in some studies, supernatant was collected for analysis of cytokine protein levels by ELISA. In the studies in which the cells were given a pulse of LPS, …
