Until now, microbicidal gels had proved most effective, although they should be applied before intercourse, which compromised their employment in many…

Scientists Successfully Reprogram HIV Cells

In the world there is a very small group of people who is immune to the HIV virus that causes AIDS . For years, scientists have attempted to replicate this natural resistance. Now researchers at the University of Pennsylvania, in the United States, managed to genetically engineer the immune cells of 12 patients with HIV to make them resistant to the virus. Using a relatively new techniques, scientists edited the genome of the cells in the immune system and removed a protein that makes most people susceptible to the virus. To do this, patients who participated in the research published…
