Lipopolysaccharide
Lipopolysaccharides (LPS), also known as lipoglycans, are large molecules consisting of a lipid and a polysaccharide joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria, act as endotoxins and elicit strong immune responses in animals.

Scientists reveal important clues to how bacteria and viruses are identified as enemies
A new research report in the October 2010 print issue of the Journal of Leukocyte Biology sheds important light on how our immune systems detect invading organisms to be destroyed and removed from our bodies. The information from t ...

Using a molecular switch to turn on cancer vaccines
The immune system is capable of recognizing tumor growth, and naturally mounts an anti-cancer defense. Dendritic cells (DCs) can take up tumor-derived molecules (antigens) and present them to T cells, and those "primed" T ...
