Dr. Ho takes a molecular virology approach to examine HIV persistence and develop HIV cure strategies. Using clinical samples from HIV-infected individuals, the Ho lab investigates host-HIV interactions with particular interests in single genome HIV proviral and vial sequencing, HIV epigenetic silencing, T cell biology and immune escape mechanisms. Dr. Ho, as an infectious disease attending physician in Taiwan, received her PhD and postdoctoral training at Johns Hopkins University School of Medicine. She was a tenure track instructor (2016) and then an assistant professor (2017) at Johns Hopkins School of Medicine before she joined Yale School of Medicine in 2017.

The battle: HIV versus host restriction and immune clearance

Cells containing hypermutated HIV proviruses (red) may distract CD8+ T cells (green) from killing the cells containing infectious HIV (red). Cells containing proviruses with large internal deletions (blue) may expand over time due to lack of viral cytopathic effect and immune selection. Figure illustrated by Timothy Phelps.
