Breakthrough in research on HIV, claim scientists

Researchers have decoded a system that renders certain types of immune cells impervious to HIV infection, paving way for its possible eradication from the body.

The researchers say the discovery points toward a new approach to eradicating HIV from the body, Proceedings of the National Academy of Sciences reported.

"For decades, we've seen conflicting reports on whether each of the components helped protect cells from viruses," said James Stivers, from the Johns Hopkins University.

"By plotting how much of each are found in different types of cells, as well as the cells' response to HIV, we learned that both are needed to get the protective effect," Stivers said in a statement.

DNA's code is made up of four building blocks called nucleotides, commonly abbreviated A, T, G, and C.

Stivers says, the study identifies a new pathway that could restrict HIV infection in non-dividing cells.
