The results of a new study into HIV (Human Immunodeficiency Virus), published in the journal Nature Immunology, suggest that the certain cells can block an attack from HIV by 'starving' the virus of the essential chemicals for replication.
According to BBC Science, the research rests on the fact that a virus cannot replicate on its own but must occupy a host cell to do so. When a virus occupies a cell it takes over the 'operations' of the cell and uses the cell as a factory to create replicate viruses.
The study in Nature Immunology explains that some cells can inactivate certain aspects of their own cellular mechanism which then prevents the HIV virus from replicating. There is a possibility that this research could for the basis of a new HIV antiviral.
