A quantitative approach for measuring the reservoir of latent HIV-1 proviruses [PDF]

open access: yesNature, 2019
A stable latent reservoir for HIV-1 in resting CD4+ T cells is the principal barrier to a cure1-3. Curative strategies that target the reservoir are being tested4,5 and require accurate, scalable reservoir assays.
