Major Areas of Research
- Cellular immune response to HIV, SARS-CoV-2 and other infections
- Mechanisms of durable immunologic control of HIV in rare patients
- Basic immunology of vaccine-induced responses
- Studies in a cohort of People Living with HIV Infection in Liberia, West Africa
Program Description
The major focus of the Cellular Immune Response Unit/HIV-Specific Immunity Section is identification of the mechanisms of an effective cellular immune response to HIV and other viral infections. Investigations are performed by various techniques on samples from rare patients, termed long-term nonprogressors (LTNPs) or elite controllers, who have exhibited spontaneous control of HIV replication for decades. Detailed characterization of their virus-specific T-cell responses is a critical step toward the development of effective vaccines and immunotherapies and provides fundamental insights into the regulation of human immune responses in viral infection and other disease states.
Biography
Education
M.D., 1993, University of Miami Leonard M. Miller School of Medicine, Miami, FL
In 1997, Dr. Migueles came to the National Institute of Allergy and Infectious Diseases as a Clinical Associate in the Laboratory of Immunoregulation and was commissioned as a Medical Officer in the U.S. Public Health Service (USPHS). He became a Staff Clinician in 2005, Senior Research Physician in 2017 and Head of the Cellular Immune Response Unit in 2019. Dr. Migueles was promoted to CAPT (0-6) in the USPHS in 2010. He maintains active certification in Internal Medicine and Infectious Diseases (current diplomate, American Board of Internal Medicine).
