WebJul 21, 2000 · Studies using cultured THP-1 monocyte/macrophages showed that the hydrophobic bile acid chenodeoxycholate, a well established potent repressor of CYP7A1, induced the expression of mRNAs encoding interleukin 1 (IL-1) and tumor necrosis factor alpha (TNFalpha). Macrophages exist in “resting” states and various forms of activation/polarization in vitro and in vivo. M1 macrophages are primed with microbial products like LPS and the cytokine IFN-γ and subsequently secrete many pro-inflammatory cytokines including TNFα, IL6, IL12, IL18 and IL1β (135). In contrast, IL4 … See more Phagocytosis is a receptor-mediated process designed to engulf and destroy large target cells, including microbes, from the body. Professional phagocytes possess specialized receptors that can engage with the … See more The intracellular signaling events that lead to NF-κB activation and pro-inflammatory cytokine gene expression in macrophages is best understood for TLRs and is described in several … See more Many signaling proteins overlap during phagocytosis and NF-κB activation pathways, yet the type of pro-inflammatory cytokines and magnitude of the secreted cytokine levels varies widely.
