Cells natural defense against HIV

Scientists (at The Ohio State University Comprehensive Cancer Center, et al.) have discovered a previously unknown mechanism that cells use to fight off the human immunodeficiency virus (HIV), the cause of AIDS. The findings indicate that two proteins that normally help repair cellular DNA can also destroy the DNA made by HIV after it enters a human cell. This HIV DNA is essential for the virus to survive and reproduce. The published study is referenced at biologynews.net.
