High school students can access original scientific research articles on the Internet, but may have trouble understanding them. To address this problem of online literacy, the authors developed a computer-based prototype for guiding students’ compr

Under physiological conditions, lipopolysaccharide (LPS) activation of cells involves the LPS binding protein (LBP) and either membrane or soluble CD14. We find LPS forms a ternary complex with LBP and membrane CD14 (mCD14). Subsequent to complex for

Recent work has identified two proteins that work together to enable many cell types to respond to endotoxin. These two proteins, lipopolysaccharide (LPS) binding protein (LBP) and CD14, also participate in cellular internalization of endotoxin, whic

Mitogen-activated protein (MAP) kinase cascades represent one of the major signal systems used by eukaryotic cells to transduce extracellular signals into cellular responses. Four MAP kinase subgroups have been identified in humans: ERK, JNK (SAPK),

Endotoxin (lipopolysaccharide; LPS) activates a wide variety of host defense mechanisms. In mammals LPS binding protein (LBP) and CD14 interact with LPS to mediate cellular activation. Using sucrose density gradients and a fluorescent endotoxin deriv

We examined the binding interactions of the methylation-dependent chemotaxis receptors Tsr and Tar with the chemotaxis-specific protein kinase CheA and the coupling factor CheW. Receptor directly bound CheW, but receptor-CheA binding was dependent up

An essential step in the signal transduction pathway of Escherichia coli is the control of the protein kinase activity of CheA by the chemotaxis receptor proteins. This control requires the participation of the CheW protein. Although the biochemical
