Major Areas of Research

  • Contribution of B cells to HIV pathogenesis
  • Characterization of virus-specific B-cell responses in HIV-infected individuals
  • Pathogenesis of B cells in immune-mediated diseases, particularly primary immune deficiencies
  • Characterization of B-cell responses to emerging pathogens, including SARS-CoV-2

Program Description

The primary focus of our research program is to study the role of B cells in the pathogenesis of HIV disease, with the goal of filling gaps in knowledge regarding humoral immunity against the virus. This knowledge is critical to the development of an effective antibody-based vaccine and for advancement of immunotherapeutic interventions in HIV-infected individuals. Our approach involves assessing transcriptional, phenotypic, and functional attributes of B cells that circulate in the peripheral blood and those that reside in tissues, particularly lymph nodes and the bone marrow. A major focus of our research also includes identifying and characterizing various subsets of B cells in blood and lymphoid tissues of healthy individuals and those that are overexpressed at various stages of HIV infection. We have shown that several of these subsets may be responsible for various manifestations associated with HIV disease, including hypergammablobulinemia, inadequate response to vaccination, as well as loss of homeostasis and lymphopenia. Another long-term goal is to apply our knowledge of B cells in HIV to other human diseases in which B cells play a pathogenic role and to investigate B-cell correlates of protection to emerging pathogens, including SARS-CoV-2.



Ph.D., 1996, University Laval, Quebec City, Quebec, Canada

Dr. Moir received her Ph.D. in immunology and microbiology from the University Laval, Quebec City, Quebec, Canada, in 1996. Her Ph.D. studies were supported by a scholarship from the National Health Research and Development Program of Canada. In 1996, Dr. Moir came to the NIAID Laboratory of Immunoregulation (LIR) as a Visiting Fellow. Dr. Moir was appointed to the position of Staff Scientist in 2006, with honorific title of Associate Scientist in 2010. In 2009, the National Institutes of Health (NIH) launched a new recruiting program named for the late Earl Stadtman, an NIH biochemist who mentored several Nobel laureates. Dr. Moir was selected as one of the 2014-2015 Earl Stadtman Investigators and received a tenure track investigator position in the LIR in August 2015. In 2020, Dr. Moir became a tenured senior investigator and chief of the B-Cell Immunology Section in the LIR.
