Research Summary

Defining the mechanisms of HIV replication and understanding the role of immune cells and host factors that participate in the process are essential for developing effective strategies to eradicate HIV infection. Dr. Wu’s lab studies the molecular and cellular mechanisms of HIV replication, virus interaction with host factors and anti-HIV innate immunity. The lab focuses on the molecular and cellular mechanisms underlying HIV-1 restriction by the host protein SAMHD1, which is the first identified mammalian dNTP triphosphohydrolase (dNTPase). We also investigate functional significance and the mechanisms by which N6-methyladenosine (m6A) modification of HIV-1 RNA regulates viral gene expression in immune cells. Our basic studies can lay the foundation to facilitate the development of more effective interventions against HIV infection.

Our current NIH-funded projects are:

1) SAMHD1-mediated regulation of HIV-1 innate immunity and viral gene expression. We use interdisciplinary approaches to further understand the mechanisms by which SAMHD1 regulates antiviral innate immune responses and viral gene expression in primary myeloid and CD4+ T cells. These studies aim to reveal novel physiological functions of SAMHD1 during HIV-1 infection of primary target cells, which are beyond its known function in restricting virus replication.

2) Mechanisms of HIV-1 RNA methylation in regulating viral replication. We investigate the molecular mechanisms by which m6A modification of HIV-1 RNA regulates viral gene expression and replication in primary CD4+ T-cells. Investigations of the HIV-1 RNA m6A modification and interactions with host proteins represent a new area of HIV-1 RNA biology, which can facilitate therapeutic development against HIV-1 infection.
