When the human immunodeficiency virus infects cells, it can either exploit the cells to start making more copies of itself or remain dormant -- a phenomenon called latency. Keeping these reservoirs latent is a challenge. A new paper has found a way to look for chemicals that can keep the virus suppressed into its dormant state. from Top Health News -- ScienceDaily https://ift.tt/3d1uXPV via IFTTT
