LIPID A and BACTERIAL LIPOPOLYSACCHARIDES
1. Structure and Occurrence The envelope of Gram-negative bacteria, including those of human pathogens such as Escherichia coli and Salmonella enterica, is composed of two distinct lipid membranes: an inner membrane, consisting of glycerophospholipids, and a highly distinctive outer membrane. The latter is an asymmetric bilayer, the outer leaflet of which in most species consists predominantly ...
متن کاملHemagglutination Induced by Viruses *
Since the original demonstration of the hemagglutination induced by influenza virus,, 118 a number of other important viruses have been reported as causing the agglutination of chicken erythrocytes. Specific agglutination of these red blood cells has been observed with vaccinia virus,21 the virus of Newcastle disease,1 that of fowl plague,17 variola virus,22 and mumps virus.'6 It has also been ...
متن کاملBiological activities of lipopolysaccharides and lipid A from Rhodospirillaceae.
The lipopolysaccharides and free lipid A from several strains of Rhodospirillaceae were assayed comparatively with those of Enterobacteriaceae in a number of biological tests. Free lipid A's from Rhodopseudomonas gelatinosa and Rhodospirillum tenue exhibited strong serological cross-reactions with each other and with free lipid A from Salmonella. Lipid A's from Rhodopseudomonas viridis and Rhod...
متن کاملMACROPHAGE STIMULATION BY BACTERIAL LIPOPOLYSACCHARIDES II. Evidence for Differentiation Signals Delivered by Lipid A and by a Protein Rich Fraction of Lipopolysaccharides* BY WILLIAM F. DOE,$ SOU
Bacterial lipopolysaccharides (LPS) I stimulate mouse peritoneal macrophages to lyse tumor target cells in vitro (1-3). The mechanisms involved in the differentiation of macrophages into killer cells can now be explored by using the model described in the accompanying paper (3). In that study, purified LPS extracted from a rough mutant of Salmonella minnesota (R595) added to confluent monolayer...
متن کاملMacrophage stimulation by bacterial lipopolysaccharides. II. Evidence for differentiation signals delivered by lipid A and by a protein rich fraction of lipopolysaccharides
Stimulation of macrophages to lyse tumor cells is a property common to lipopolysaccharide (LPS) extracted from a variety of smooth and rough bacterial strains by several different preparative procedures. The relationship between macrophage stimulation and the structural characteristics of LPS is defined. In protein-free LPS, lipid A bears the stimulatory signal which results in the differentiat...
