Deep Analysis of CD4 T Cells in the Rhesus CNS During SIV Infection

Systemic HIV infection results in chronic inflammation that causes lasting damage to the central nervous system (CNS), despite long-term antiretroviral therapy (ART). Researchers studied neurocognitive outcomes in male and female rhesus macaques infected with simian immunodeficiency virus (SIV) using an ART regimen simulating suboptimal adherence; one group received no ART, and the other received ART with periodic interruptions. Using single-cell transcriptomic profiling, the researchers also identified molecular programs induced in the brain upon infection. They found that acute infection led to marked imbalance in the CNS CD4/CD8 T‑cell ratio, which persisted into the chronic phase. The studies provide insight into the role of CD4 T cells in the CNS during HIV infection. Supported by ORIP (P51OD011107, K01OD023034), NIA, NIAID, and NCI.
Effects of Pulsatile Intravenous Follicle-Stimulating Hormone Treatment on Ovarian Function in Women With Obesity

By performing intravenous (IV) administration of pulsatile recombinant follicle-stimulating hormone (FSH), researchers established conditions for effective hypothalamic suppression in women with normal and high body mass index (BMI). In women with obesity, the treatment resulted in E2 and inhibin B levels comparable to those in normal-weight women. This work offers a potential strategy to mitigate some of the adverse effects of high BMI on fertility, assisted reproduction, and pregnancy outcomes. Supported by ORIP (K01OD026526), NIA, and NICHD.
