"Genetically-intact HIV hides in the same cells of the human immune system that are supposed to attack and destroy pathogens, scientists at Westmead Institute for Medical Research, Sydney University, discover in a new study.
Previously, it was thought that HIV hides primarily in central memory T-cells during effective anti-HIV therapy. But, in the study published this month (19 October) in Cell Reports, the scientists show that replication-competent HIV persists in specific subsets of CD4+ immune memory T-cells.
HIV infects white blood cells known as T lymphocytes, particularly the CD4+ T cells that recognise infection and get the immune system to respond. Following HIV infection, if anti-HIV therapy is not initiated, the number of CD4+ T cells in the blood begins to fall, though the process may be slow."
