Role of galectin-3 in classical and alternative macrophage activation in the liver following acetaminophen intoxication.
Inflammatory macrophages have been implicated in hepatotoxicity induced by the analgesic acetaminophen (APAP). In these studies, we characterized the phenotype of macrophages accumulating in the liver following APAP intoxication and evaluated the role of galectin-3 (Gal-3) in macrophage activation. Administration of APAP (300 mg/kg, i.p.) to wild-type mice resulted in the appearance of two dist...
متن کاملRegulation of alternative macrophage activation by galectin-3.
Alternative macrophage activation is implicated in diverse disease pathologies such as asthma, organ fibrosis, and granulomatous diseases, but the mechanisms underlying macrophage programming are not fully understood. Galectin-3 is a carbohydrate-binding lectin present on macrophages. We show that disruption of the galectin-3 gene in 129sv mice specifically restrains IL-4/IL-13-induced alternat...
متن کاملTemporal Characterization of Microglia/Macrophage Phenotypes in a Mouse Model of Neonatal Hypoxic-Ischemic Brain Injury
Immune cells display a high degree of phenotypic plasticity, which may facilitate their participation in both the progression and resolution of injury-induced inflammation. The purpose of this study was to investigate the temporal expression of genes associated with classical and alternative polarization phenotypes described for macrophages and to identify related cell populations in the brain ...
متن کاملModulating Role of Panax Ginseng in Phase - II Reaction of Hepato - Biotransformation in Albino Rats Following Mercuric Chloride Intoxication
Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...
متن کاملSingle administrations of high and low doses of acetaminophen causes different effects on COX-2 gene expression and on tissue damage in liver and kidneys
Introduction: High dose of acetaminophen (APAP) is known to have hepatotoxic and nephrotoxic effects and studies show that this toxicities are dependent on the function of phase I bioactivation enzymes- Cyp450- and phase II biotransformation enzymes especially glucuronosylation and sulfonation pathways. However, the role of cyclooxygenase (COX) as an inflammatory mediator in toxic effects of AP...
