“Inter-kingdom signaling in the GI tract: There`s a lot of talking going
... (Host: Prof. Shashi Murthy) ABSTRACT The human gastro-intestinal (GI) tract is colonized by approximately 1014 bacterial cells that belong to about 400 different species and co-exist with host cells. However, introduction of pathogens such as enterohemorrhagic E. coli (EHEC) disturbs this homeostasi ...

Lipopolysaccharide
Lipopolysaccharides (LPS), also known as lipoglycans and endotoxin, are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria, and elicit strong immune responses in animals.The term lipooligosaccharide (""LOS"") is used to refer to a low molecular weight form of bacterial lipopolysaccharides.
