National Science and Technology Key Projects on “Major Infectious Diseases such as HIV/AIDS, Viral Hepatitis Prevention and Treatment”

Project 1: The Establishment of Detection Platform for Viral Infection and Immune Response in the Respiratory System and the Central Nerve System

Project leader: Ke Lan*

Project profile:
Project number: 2009ZX10004-105
Validity: 2009/01---2010/12

Infectious diseases have been a growing severe menace to the public health and national security. In the recent thirty years, more than forty new pathogens have been identified and most of them are viruses. To date, infectious diseases have been the disease with the highest incidence in the world and they were the second cause to more than 50 million deaths globally each year. They damaged human's health, largely hampered and even destroyed developments of economy and society. In case of epidemic, fast and precise identification of pathogen is crucial to the control of disease. 

Development of platform for pathogen identification based on high-throughput technology will facilitate the prevention and control of disease. To develop such platform, different technologies on virology, genomics, bioinformatics, immunology and other domains should be integrated. The aim of the project is to associate experts from different fields and set up a platform to detect the viruses causing infections in respiratory tract and central nerve system. The project will later provide the base for the following expansion of the platform.

Project 2: Studies of biology of difficult-to-treat hepatitis C and development of novel strategies for its treatment

Project Leader: Prof. Jin ZHONG, Institut Pasteur of Shanghai, Chinese Academy of Sciences

Project profile:
Project No. 2008ZX10002-014
Validity: 2008/10---2010/12

Hepatitis C virus (HCV) can cause acute and chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. China is one of high hepatitis C incidence areas, and has the biggest population of HCV infected patients in the world. Unfortunately, there is no vaccine to prevent HCV infection and no antiviral drug specifically against HCV at the present. PEG-interferon and ribavirin combination therapy, the only treatment against HCV now, is not satisfying for its efficacy, duration, cost and side-effects.

The overall objective of this grant is to uncover biological characteristics of difficult-to-treat hepatitis C, especially with Chinese isolates, and to explore the molecular mechanisms underlying viral pathogenesis and poor sustained virological response to the interferon therapy through studying virology, cell biology, immunology and clinical aspects of HCV infection, which would provide novel anti-viral drug targets and strategies for HCV treatment. For this aim, we will try to develop the molecular clones, cell culture models and small animal models for Chinese HCV isolates, and then establish advanced technical platforms for the antiviral drug and vaccine development with our own intellectual property. We hope that our research in this grant proposal will ultimately contribute to the prevention and treatment of hepatitis C in China.
