Salk Institute researchers, in collaboration with the National Institutes of Health, have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV. Their findings reveal how changes to the 3D structures of integrase, an HIV protein, can lead to Dolutegravir resistance and how other compounds may be able to overcome this resistance. ....
Proteins could become targets for long-acting therapies for patients suffering from AIDS-related illnesses HIV-1, which causes AIDS, navigates a labyrinth of immune sensors and anti-viral attackers in order to reach a target-cell nucleus, where it permanently integrates into human DNA and spreads infection. How the virus traffics through this hostile environment has been a relative “black box” of mystery compared to other parts of the life cycle. “We’re trying to understand the cellular proteins – which ones are helping this (HIV-1 core) structure travel all the way from the entry point to the nucleus, where HIV-1 permanently integrates into the human genome,” said Kvaratskhelia, a professor of medicine. ....
