Targeting Liver Tumors with Oncolytic Viruses via the Hepatic Artery

Abstract

The video demonstrates locoregional delivery of oncolytic viruses through hepatic arterial injection as a therapeutic approach for hepatocellular carcinoma. These viruses selectively replicate in tumor cells, inducing cell lysis and releasing tumor cell-associated antigens. This process triggers immunogenic cell death, inducing an anti-tumor response.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparations before beginning surgery Sterilize surgical instruments (i.e., by autoclaving). Dilute the virus to the appropriate concentration, which will vary depending on the toxicity of the specific virus being used and the susceptibility of the rat strain. NOTE: For example…
Representative Results
Figure 1. Photographs of the hepatic arterial infusion procedure. A laparotomized rat demonstrates the placement of the abdominal wall retractor and gauze swabs (A). After lifting out the hepatic lobes, the common hepatic artery (designated CHA) and gastroduodenal artery (designated GA) are identified and dissected (B). After ligating the distal end of the gastro…
