Research Overview

The Ian Potter Hepatitis research Laboratory has had a major interest in the structure, replication and assembly of three of the major hepatitis viruses (hepatitis B, hepatitis A and hepatitis E) for many years, with the long-term goals of using this increased understanding for improved control of disease through vaccines, diagnostics and antivirals. In the course of our development of rapid, point-of-care tests for hepatitis E and hepatitis A infection, we have developed unique expertise for development of tests against a range of acute viral and bacterial diseases, in a continuing partnership with Select Vaccines Ltd. These tests allow the diagnosis of patient disease using a finger prick sample of blood within 10-15 min, with minimal training and no equipment, and are especially useful in resource-poor or emergency settings. This expertise has also provided part of the background research for our work on a new point-of-care test for monitoring of CD4 T-cell numbers in HIV-infected patients, in collaboration with Suzanne Crowe and Robyn Lloyd (Burnet) and Alan Landay (Rush University, Chicago).

 

Research Objectives

• Understanding the assembly and disassembly of hepatitis B virus
• Identifying the interactions of hepatitis A virus and hepatitis B virus with polarized epithelial cells
• Development of ELISA and rapid point of care tests, for hepatitis and other significant diseases, including monitoring of CD4 T-cells

 

Research Highlights

• Identifying the fusion peptide of duck hepatitis B virus, pointing the way to this peptide as a potential target for antiviral drugs against the human hepatitis B virus
• Identifying the mechanisms by which hepatitis B virus can cross the cellular barriers to cause infection, and the first demonstration that hepatitis A virus can also cross these barriers to spread infection
• Development of world-first rapid point-of-care test for acute syphilis infection, and progress towards similar tests for influenza (in collaboration with WHO Influenza Centre) and monitoring of CD4 T-cells (in collaboration with Prof Suzanne Crowe, Burnet, and Prof Alan Landay, Rush University, Chicago)
