Leishmania major UDP-sugar pyrophosphorylase salvages galactose for glycoconjugate biosynthesis
Leishmaniases are a set of tropical and sub-tropical diseases caused by protozoan parasites of the genus Leishmania whose severity ranges from self-healing cutaneous lesions to fatal visceral infections. Leishmania parasites synthesise a wide array of cell surface and secreted glycoconjugates that play important roles in infection. These glycoconjugates are particularly abundant in the promasti...
متن کاملThe scavenger receptor MARCO is involved in Leishmania major infection by CBA/J macrophages.
CBA/J mice are resistant to Leishmania major infection but are permissive to L. amazonensis infection. In addition, CBA/J macrophages control L. major but not L. amazonensis infection in vitro. Phagocytosis by macrophages is known to determine the outcome of Leishmania infection. Pattern recognition receptors (PRR) adorning antigen presenting cell surfaces are known to coordinate the link betwe...
متن کاملScavenger receptor-mediated uptake and metabolism of lipid vesicles containing acidic phospholipids by mouse peritoneal macrophages.
We studied the mechanism of uptake and metabolism of exogenous phospholipids in mouse peritoneal macrophages using vesicles composed of various phospholipids and cholesterol. Macrophages in culture were found to actively incorporate and metabolize phosphatidylcholine/cholesterol vesicles containing small amounts of acidic phospholipids such as phosphatidylserine, phosphatidylinositol, or phosph...
متن کاملToll-like receptor 2 dependent immunogenicity of glycoconjugate vaccines containing chemically derived zwitterionic polysaccharides.
Group B Streptococcus (GBS) causes serious infection in neonates and is an important target of vaccine development. Zwitterionic polysaccharides (ZPS), obtained through chemical introduction of positive charges into anionic polysaccharides (PS) from GBS, have the ability to activate human and mouse antigen presenting cells (APCs) through toll-like receptor 2 (TLR2). To generate a polysaccharide...
متن کاملSynthesis and evaluation of the first cis-cyclobutane-containing receptor for lipid A.
The first example of a designed receptor containing a cis-1,3-disubstituted cyclobutane ring has been synthesized. This molecule binds diphosphoryl lipid A (a conserved portion of the Gram-(-) bacterial cell membrane, and the causative agent of septic shock) with an affinity comparable to previously described ter-cycloalkane based lipid A-binding compounds.
