Publication number: 20240277861Abstract: An anti-HBV agent according to the present invention contains as an active ingredient a substance that binds to LIPG and inhibits the function(s) of LIPG. The inventors of the present application have found that LIPG is a factor playing an important role in HBV attachment and uptake, and functions as a cofactor that supports HBV entry into cells independently of NTCP, and also contributes to HBV proliferation in cells. T The LIPG-binding substance binds to LIPG on the surface of liver cells to inhibit HBV attachment and uptake into cells and, when delivered into liver cells, binds to intracellular LIPG to block any step(s) in the intracellular HBV proliferation process, thereby exerting an anti-HBV activity.Type: ApplicationFiled: July 22, 2022Publication date: August 22, 2024Applicant: PUROTECH BIO, INC.Inventors: Hiroshi YANAGAWA, Noriko TABATA, Yuko YONEMURA, Mayuko IDE, Satoru ITO, Shuichi KANEKO, Masao HONDA, Takayoshi SHIRASAKI, Kazuhisa MURAI, Hikari OKADA
