WebActivation of macrophages via LPS–LPS-binding protein (LPS-LBP) to surface CD14 receptors promotes expression of TNF-α, IL-1, and IL-6, which trigger signal transduction for the expression of genes that serve to encode inflammatory effects, such as NF-κB and activator protein-1. In time, more TNF-α and inflammation result [29].
