| Research Abstract |
In order to make the transgenic mouse to be infected by HCV, we created the transgenic (Tg) mouse in which human four factors were expressed in the mouse hepatocytes. After confirming that HCV E2 protein bound to the hepatocytes of Tg mouse, we injected HCV from the patient serum. We measured the viral genome RNA copy number in the blood by the qRT-PCR method. Result showed that HCV cannot infect to the hepatocytes of Tg mouse. We investigated whether mouse inhibitory proteins inhibit the entry of HCV into hepatocytes and/or another essential human factor is necessary for the entry of HCV. Results suggest that the mouse Cd81 and Ocln proteins inhibit the entry process and that human NPC1L1 protein enhances the entry of the virus.
