Researchers have discovered the protein that helps HIV to evade the body's defence system, an advance that may help stop the deadly virus in its tracks. HIV-1 infects and kills immune system cells, including T cells and macrophages that were used in the study. This cripples the immune system, making the patient vulnerable to common bacteria, viruses and other pathogens that are usually harmless in people with healthy immune systems. After HIV-1 enters a cell, it has to work its way through the cytoplasm to the nucleus. Once inside the nucleus, HIV-1 takes control of the cell and makes additional HIV-1 copies.
