Clinical Interest
Research Interest 1. Development of Molecular Imaging Technology for Visualizing HIV-1 Reservoirs in Vivo

We engineer lentivirus including human, simian and feline immunodeficiency virus (HIV, SIV and FIV) as "Trojan Horse" to carry molecular imaging reporter to investigate where the virus goes and when it infect the target cells using in vivo imaging technologies based on optical bioluminescence imaging (BLI), MRI and PET.

2. Visualizing therapeutic nanoparticles for HIV-1 Eradication.

We use a novel gene editing technique called CRISPR/Cas9, which effectively targets the HIV-1 genome using small guidance RNAs (gRNAs), for eradicating HIV-1 in a preclinical setting. Non-invasive in vivo imaging methods are used to visualize the biodistribution and the effectiveness of therapeutic nanoparticles to excise HIV-1 genome from its host cells as an innovative eradication strategy.

3. Visualizing immune cells and HIV-1 infection

We visualize the interaction between immune cells and HIV-1 mucosal transmission, e.g. intravaginal transmission, and, drug-resistant HIV-1 mutants and Pre-Exposure Prophylaxis (PrEP) using 19F MRI and BLI.
