Researchers discover gene that blocks HIV

A team of researchers at the University of Alberta has discovered a gene that is able to block HIV, and in turn prevent the onset of AIDS.

Stephen Barr, a molecular virologist in the Department of Medical Microbiology and Immunology, says his team has identified a gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus.

"When we put this gene in cells, it prevents the assembly of the HIV virus," said Barr, a postdoctoral fellow. "This means the virus cannot get out of the cells to infect other cells, thereby blocking the spread of the virus."

Barr and his team also prevented cells from turning on TRIM22 - provoking an interesting phenomenon: the normal response of interferon, a protein that co-ordinates attacks against viral infections, became useless at blocking HIV infection.
