Despite the large number of patient population, effective treatments for fibrosis have been limited. Diverse intracellular signaling pathways are related with fibrosis, posing challenges in identifying suitable therapeutic targets.<br \/>\nResearchers have previously discovered significant inhibitory effects on fibrosis with reovirus, developed as anticancer agents. <a href=\"https:\/\/bionauts.jp\/?p=658\" target=\"_blank\" rel=\"noopener\">https:\/\/bionauts.jp\/?p=658<\/a><br \/>\nIn liver fibrosis, reovirus are taken up by hepatic stellate cells, exerting a regression of fibrotic effect, including the normalization of cell function such as migration ability, expression of quiescent markers, and fatty storage capacity.<br \/>\nRIG-I, known as a receptor for reovirus, functions as a pattern recognition receptor within the cytoplasm, contributing to the innate immune system. Drug development efforts targeting RIG-I have primarily focused on cancer and infectious diseases, utilizing chemically synthesized dsRNA and small molecules as ligands.<br \/>\nResearchers newly found antifibrotic effect of ligand for RIG-I in this study.<\/p>\n<h3><strong>Data<\/strong><\/h3>\n<ul>\n<li>3p-hairpin RNA (3p-hpRNA), a dsRNA derived from influenza A sequence, was employed as a ligand for RIG-I.<\/li>\n<li>3p-hpRNA markedly reduced gene expression of fibrosis markers such as COL1A1 and ACTA2 in TGF-\u03b2 activated human liver stellate cells (LX-2), human lung fibroblasts (NHLF, MRC-5) and human skin fibroblasts (NHDF), respectively.<\/li>\n<li>In vivo experiments are in the planning.<\/li>\n<\/ul>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><a href=\"http:\/\/bionauts.jp\/wp-content\/uploads\/2024\/07\/TT-04848.png\"><img decoding=\"async\" loading=\"lazy\" class=\"alignleft wp-image-3809 size-full\" src=\"http:\/\/bionauts.jp\/wp-content\/uploads\/2024\/07\/TT-04848.png\" alt=\"\" width=\"915\" height=\"341\" srcset=\"https:\/\/bionauts.jp\/wp-content\/uploads\/2024\/07\/TT-04848.png 915w, https:\/\/bionauts.jp\/wp-content\/uploads\/2024\/07\/TT-04848-300x112.png 300w, https:\/\/bionauts.jp\/wp-content\/uploads\/2024\/07\/TT-04848-768x286.png 768w\" sizes=\"(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><strong>Patent<\/strong><\/h3>\n<ul>\n<li>Applied (unpublished)<\/li>\n<\/ul>\n<h3><strong>Principal Investigator &amp; Academic Institution<\/strong><\/h3>\n<p>Prof. Fuminori SAKURAI (Department of Pharmacy, Graduate School of Medicine, Kindai University))<\/p>\n<h3><strong>Expectations<\/strong><\/h3>\n<p><u>TECH MANAGE CORP.<\/u> is looking for a pharmaceutical company\/start-up that is interested in the development of this novel therapeutics for fibrosis.
