Lipoteichoic acid induces delayed protection in the rat heart: A comparison with endotoxin.
Classic ischemic preconditioning transiently (30 to 120 minutes) protects the myocardium against subsequent lethal ischemia/reperfusion injury. After dissipation of this acute protection, a second window of protection (SWOP) appears 12 to 24 hours later; this SWOP lasts up to 3 days. Several triggers induce a SWOP, including brief repetitive cycles of coronary artery occlusion, rapid ventricula...
متن کاملStaphylococcal lipoteichoic acid inhibits delayed-type hypersensitivity reactions via the platelet-activating factor receptor.
Staphylococcus aureus infections are known triggers for skin inflammation and can modulate immune responses. The present studies used model systems consisting of platelet-activating factor receptor-positive and -negative (PAF-R-positive and -negative) cells and PAF-R-deficient mice to demonstrate that staphylococcal lipoteichoic acid (LTA), a constituent of Gram-positive bacteria cell walls, ac...
متن کاملProtection against Staphylococcus aureus by antibody to the polyglycerolphosphate backbone of heterologous lipoteichoic acid.
Type 1 lipoteichoic acid (LTA) is present in many clinically important gram-positive bacteria, including enterococci, streptococci, and staphylococci, and antibodies against LTA have been shown to opsonize nonencapsulated Enterococcus faecalis strains. In the present study, we show that antibodies against E. faecalis LTA also bind to type 1 LTA from other gram-positive species and opsonized Sta...
متن کاملLipoteichoic acid as an inducer of acute uveitis in the rat.
PURPOSE To examine the capacity of lipoteichoic acid (LTA) to induce intraocular inflammation in the rat. METHODS LTA obtained from Staphylococcus aureus and three different streptococcal species were suspended in saline solution in various concentrations and were injected into one footpad of female Lewis rats. The uveitic changes were assessed by conventional clinical and histopathologic pro...
متن کاملLipoteichoic acid from Listeria monocytogenes.
A lipoteichoic acid (LTA) was extracted from Listeria monocytogenes (serotype 1) by phenol-water partition and isolated by gel-filtration chromatography. The LTA exhibited amphiphilic properties by changes in gel-filtration mobility in the presence of detergent buffers and after mild base hydrolysis. In a hemagglutination assay, Listeria LTA bound antibody prepared against a known LTA from Stre...
