Professor Weiss and the study of HIV/AIDS, Professor Weiss is a leading international authority on HIV and AIDS, having been responsible for some of the most important research breakthroughs in the field. His team identified CD4 as the cell surface receptor for the HIV virus, and contributed to the development of the first screening test to detect HIV in blood banks and prevent transmission of the disease through transfusions.
Professor Weiss was awarded the Ernst Chain Award, in recognition of his contribution to HIV/AIDS research, in 2007. He currently leads a $25 million research consortium funded by the Bill and Melinda Gates Foundation which is searching for a vaccine against HIV.
|A genetic variation which evolved to protect people of African descent against malaria has now been shown to increase their susceptibility to HIV infection by up to 40 per cent, according to new research. Conversely, the same variation also appears to prolong survival of those infected with HIV by approximately two years.|
The discovery marks the first genetic risk factor for HIV found only in people of African descent, and sheds light on the differences in genetic makeup that play a crucial role in susceptibility to HIV and AIDS.
The research, published today in Cell Host & Microbe, was co-authored by Professor Robin Weiss, UCL Infection and Immunity, who worked with colleagues in the US to analyse data from a 25-year study of thousands of Americans of different ethnic backgrounds.
The gene that the research focused on encodes a binding protein found on the surface of cells, called Duffy Antigen Receptor for Chemokines (DARC).
