The latent HIV-1 reservoir persists with antiretroviral therapy (ART), and assays for quantifying intact proviruses in nonhuman primate models are needed. Researchers used a simian–human immunodeficiency virus (SHIV) intact proviral DNA assay to describe viral decay during the first year of ART in female rhesus macaques. Their results suggest that intact SHIV genomes in circulating CD4+ T cells undergo biphasic decay during the first year of ART, with a rapid first phase and a slower second phase. These findings can provide insight for future studies using SHIV models, as well as new cure interventions. Supported by ORIP (R01OD011095) and NIAID.
Impaired Placental Hemodynamics and Function in a Non-Human Primate Model of Gestational Protein Restriction

Maternal malnutrition is a global health epidemic that adversely affects fetal outcomes and results in long-term health complications in children. Investigators used a previously developed model in nonhuman primates for gestational protein restriction to study the impact of undernutrition, specifically protein deficiency, on placental function and pregnancy outcomes. The data demonstrate that a 50% protein-restricted diet reduces maternal placental perfusion, decreases fetal oxygen availability, and increases fetal mortality. These alterations in placental hemodynamics could partly explain human growth restriction and stillbirth seen with severe protein restriction in developing countries.
