The nanoparticles, incorporating NO donor molecules (S\u2010nitrosoglutathione compound), are designed for liver delivery, minimizing systemic delivery of NO. The nanoparticles are decorated with vitamin A to specifically target HSCs. We demonstrate, using in vitro and in vivo experiments, that the targeted nanoparticles are taken up specifically by rat primary HSCs and the human HSC cell line accumulating in the liver. When nanoparticles, coated with vitamin A, release NO in liver cells, we find inhibition of collagen I and \u03b1\u2010smooth muscle actin (\u03b1\u2010SMA), fibrogenic genes associated with activated HSCs expression in primary rat liver and human activated HSCs without any obvious cytotoxic effects. Finally, NO\u2010releasing nanoparticles targeted with vitamin A not only attenuate endothelin\u20101 (ET\u20101) which elicites HSC contraction but also acutely alleviates haemodynamic disorders in bile duct\u2010ligated\u2010induced portal hypertension evidenced by decreasing portal pressure (\u224820%) and unchanging mean arterial pressure. This study clearly shows, for the first time, the potential for HSC targeted nanoparticle delivery of NO as a treatment for liver diseases with proven efficacy for alleviating both liver fibrosis and portal hypertension.<\/jats:p>","DOI":"10.1002\/smll.201402870","type":"journal-article","created":{"date-parts":[[2015,1,13]],"date-time":"2015-01-13T21:32:24Z","timestamp":1421184744000},"page":"2291-2304","source":"Crossref","is-referenced-by-count":117,"title":["The Use of Nanoparticles to Deliver Nitric Oxide to Hepatic Stellate Cells for Treating Liver Fibrosis and Portal Hypertension"],"prefix":"10.1002","volume":"11","author":[{"given":"Hien T.
