Determining The Relative Transmission Fitness Of Hiv-1 Subtypes A, B, C, And D, Spencer Yeung
Determining The Relative Transmission Fitness Of Hiv-1 Subtypes A, B, C, And D, Spencer Yeung

There is in vivo evidence that suggests the genetic diversity of HIV-1 subtypes influence heterosexual transmission efficiency. To recapitulate sexual transmission in vitro, blocks of genital tissue were exposed to mixtures of genetically different subtype viruses. Migrating immune cells were collected and co-cultured with a CD4+ T-cell line permissive to HIV infection (PM1) to measure dendritic cell virus transfer; HIV-exposed tissues were cultured separately. Next generation sequencing (NGS) of HIV-1 DNA was used to quantify relative infection rates of the various challenge viruses, and to assess fitness differences in infection of the tissue vs. migratory/T cell co-cultures. Our results …

Fetal growth restriction (FGR) is defined by low birth weight and contributes to a variety of adult-onset diseases with different severities between males and females. However, the effects of FGR on the pulmonary surfactant are not fully elucidated. In this thesis, first, we investigated the FGR effects on the lung function and the surfactant system at the early postnatal life. It was hypothesized that FGR contributes to alterations of lung mechanics and the surfactant system during the neonatal period. Second, we assessed the FGR effects on the surfactant system in response to sepsis in adulthood. It was hypothesized that FGR …
