CD14 is a 55 kDa cell surface glycoprotein that is preferentially expressed on monocytes/macrophages. The human CD14 cDNA encodes a 375 amino acid (aa) residue precursor protein with a 19 aa signal peptide and a C-terminal hydrophobic region characteristic for glycosylphosphatidyinositol (GPI)-anchored proteins. Human CD14 has four potential N-linked glycosylation sites and also bears O-linked carbohydrates. The amino acid sequence of human CD14 is approximately 65% identical with the mouse, rat, rabbit, and bovine proteins. CD14 is a pattern recognition receptor that binds lipopolysaccharides (LPS) and a variety of ligands derived from different microbial sources. The binding of CD14 with LPS is catalyzed by LPS-binding protein (LBP). The toll-like-receptors have also been implicated in the transduction of CD14-LPS signals. Similar to other GPI-anchored proteins, soluble CD14 can be released from the cell surface by phosphatidyinositol-specific phospholipase C. Soluble CD14 has been detected in serum and body fluids. High concentrations of soluble CD14 have been shown to inhibit LPS-mediated responses. However, soluble CD14 can also potentiate LPS response in cells that do not express cell surface CD14.
The role of TLR4 in breast cancer Toll like receptors (TLRs) are highly conserved proteins that are first known for their role in pathogen recognition and immune response activation. In order to elicit the necessary immune response in reaction to a foreign pathogen, TLRs trigger cy... Read full blog post. |
CD14 - TLR4 is my friend in battle against infections! CD14 is a well-characterized cell-activating receptor for lipopolysaccharide-binding protein (LBP) and peptidoglycan. It is an important modulator for lipopolysaccharide (LPS)-dependent signaling and is a component of the multi-protein complex contain... Read full blog post. |
CD11b: Marker for a New Type of B Cell that Participates in Cell-Mediated Immunity Think B lymphocytes just produce antibodies? Think again! Although, of course, B cells are vital for the humoral immune response, many studies in recent years have begun to uncover antibody-independent actions of B cells: regulating T cells and thus a...
