Major Areas of Research

  • Mechanisms of viral persistence in HIV-infected individuals receiving antiretroviral therapy
  • Dynamics of immunologic and virologic parameters in HIV infection
  • Therapeutic strategies aiming at achieving sustained virologic control of HIV infection

Program Description

Our research program focuses on delineation of the mechanism by which HIV persists in infected individuals receiving clinically effective antiretroviral therapy. We utilize a variety of highly sensitive cellular and molecular assays to examine the dynamics of HIV burden in subsets of CD4+ T cells and immune cells that mediate virologic control in infected individuals. We also conduct phase I clinical trials to develop safe and effective therapeutic strategies for control of HIV infection in HIV-infected individuals in the absence of daily antiretroviral drugs. 



Ph.D., Mediterranean University of Aix-Marseille II, France

Dr. Blazkova received her Ph.D. in Immunology at the Mediterranean University of Aix-Marseille II, France in 2006. Afterwards she conducted postdoctoral research at the Institute of Molecular Genetics, Academy of Sciences of the Czech Republic in Prague. In 2010, Dr. Blazkova joined the Laboratory of Immunoregulation at NIAID as a Visiting Fellow. In 2015, she worked at the Systems Biology Department, Division of Translational Medicine, Sidra Medical and Research Center, Doha, Qatar, for one year as a Senior Postdoctoral Fellow. In 2016, Dr. Blazkova returned to the NIAID and was appointed as a Staff Scientist in the HIV Immunovirology section, LIR.
