Dr. Sodroski received his MD in 1980 from Jefferson Medical College, followed by a research fellowship in Dr. William Haseltine's laboratory at DFCI. In 1984 he joined the faculty of DFCI and Harvard Medical School. His research focuses on the replication and pathogenesis of HIV, and the innate and adaptive host immune response to retrovirus infections.

ResearchHIV-1 Entry into Target Cells, Post-Entry Restrictions to Retrovirus Infection
Human immunodeficiency virus-1 (HIV-1), the cause of acquired immunodeficiency syndrome (AIDS), enters host cells by a process involving the envelope glycoproteins on the outer part of the virus and host cell receptors. Our laboratory has shown that the HIV-1 envelope glycoproteins must first bind the host receptors, CD4 and CCR5/CXCR4, and then fuse the viral membrane and the host cell membrane. This fusion allows the virus to introduce its genes into the target cell and achieve infection. An understanding of how this process occurs may open new avenues for intervention by drugs or by host immune responses. Therefore, this understanding will expedite the development of HIV-1 vaccines, microbicides, and treatments.
Once expressed in the infected cell, the HIV-1 envelope glycoproteins contribute to the killing of the cell. We are exploring the mechanisms whereby envelope glycoprotein function leads to cell death. We also are investigating the relation between this cell killing and the loss of T lymphocytes during HIV-1 infection of humans. The destruction of T lymphocytes by HIV-1 is central to inducing an immunocompromised state in infected individuals.
After entering the host cells, retroviruses encounter blocks in the cells of certain species. These blocks are mediated by a protein called TRIM5alpha, which targets the incoming viral capsid. Understanding the mechanism of TRIM5alpha-mediated restriction may allow this aspect of innate intracellular immunity to be manipulated to our advantage. Furthermore, the uncoating of the retroviral capsid is a poorly understood process. Host cell factors that modulate this process, including TRIM5alpha, are under active investigation.
