Researchers from the Montreal Clinical Research Institute may have made a crucial first step in this direction. Their recent research, outlined recently in the journal Cell Reports, focuses on boosting the levels of ‘plasmacytoid dendritic cells’ (PDCs) in the earliest stages of HIV infection.

PDCs are a specialised type of immune cell which both detects pathogens and orchestrates antiviral response, primarily by “producing large amounts of interferon, a protein that triggers a state of infection resistance in other cells, ” explains researcher Éric Cohen. HIV is able to dramatically lower the number of PDCs throughout the body as soon as it arrives through an ...
