About Me
I am an active researcher in the field of blood stem cell biology. My work primarily focuses on the expansion of human hematopoietic stem cells and understanding retrovirus behaviors. I am passionate about exploring innovative solutions in biomedical science.
Download CVResearch Interests
My research is centered around stem cell biology and virology. I explore how hematopoietic stem cells can be manipulated for better therapeutic outcomes and study retroviruses for better understanding of their pathogenesis.
Projects
HIV-1 cell-to-cell transfer and viral dissemination in myeloid cells
Most enveloped viruses encode viral fusion proteins to penetrate host cells via membrane fusion. Interestingly, many enveloped viruses, such as HIV-1 and SARS-CoV-2, can also use these viral fusion proteins to induce cell-cell fusion, both in vitro and in vivo, leading to the formation of syncytia or multinucleated giant cells (MGCs). Virus cell-to-cell spread through inducing cell-cell fusion may overcome entry and post-entry blocks in target cells and allow evasion of neutralizing antibodies.

Viruses have evolved various strategies to evade the host's innate immune response, one of which is incorporating viral proteins into virions to antagonize these immune responses and support efficient viral replication. HCMV incorporates several viral proteins, such as pUL83 (pp65) and the UL26 tegument protein, to target various stages of the IFN signaling pathway, effectively dampening the host's antiviral response. Similarly, the Ebola virus incorporates viral proteins like VP35 and VP24. With respect to HIV-1, Vpr is the only accessory protein incorporated into virions. I found that HIV-1 Vpr can directly antagonise IFN by targeting the STAT proteins.
