Major Areas of Research

  • Pathogenesis of HIV infection emphasizing mechanisms of immune reconstitution inflammatory syndrome in advanced HIV infection and of serious non-AIDS events in treated HIV-infected patients
  • Pathogenesis of idiopathic CD4 lymphocytopenia (ICL)
  • Immune-based therapeutic strategies of HIV infection and ICL
 

Program Description

The primary research focus of our group is the study of inflammatory complication in HIV including immune reconstitution inflammatory syndrome (IRIS). IRIS is an aberrant immune response, frequently with an intense inflammatory component, that can occur in the context of immune restoration in patients with HIV infection and severe CD4 lymphopenia after initiation of antiretroviral therapy (ART). Chronically treated patients on the other hand may experience non-infectious complications of HIV, including cardiovascular disease that seem to be driven by chronic residual immune activation and inflammation. The second interest is development of adjuvant immune-based therapies (IBT) to improve immune restoration in CD4 lymphopenic conditions such as HIV and idiopathic CD4 lymphopenia (ICL). ICL is a rare, likely heterogeneous condition characterized by low CD4 T-cell counts in the absence of HIV or other known infection or disease that can cause lymphopenia.

Biography

Dr. Sereti received her M.D. from the University of Athens, Greece, in 1991. She did research for one year in Dr. Greg Spear’s laboratory at Rush Presbyterian Hospital in Chicago and then completed an internship, residency, and chief residency in medicine at Northwestern University. In 1997, Dr. Sereti came to the National Institutes of Health as a clinical associate in the Laboratory of Immunoregulation. She became a staff clinician in 2003. She was appointed to a clinical tenure-track position in 2009.
