Outline of Final Research Achievements |
Currently, liver transplantation is the only way to treat the hepatic fibrosis , it is necessary to establish the other treatments. We have reported that hepatic fibrosis is inhibited by increased platelet. Also Platelets inhibit the activation of hepatic stellate cells via an adenine nucleotide and suppress the type Ⅰ collagen production. Retinoic acid has been reported to be a direct effect on hepatic stellate cells. Therefore, we attempted to selectively suppress hepatic fibrosis by creating a retinoic acid-modified adenosine encapsulating liposomes. Activation of TWNT-1 was confirmed to be suppressed by the addition of adenosine for TWNT-1. However, in the fibrosis model animals, it was difficult to prove the effectiveness of adenosine.
