About the Investigator

Dr. Betty Diamond graduated with a BA from Harvard University and an MD from Harvard Medical School. She performed a residency in internal medicine at Columbia Presbyterian Medical Center and received postdoctoral training in immunology at the Albert Einstein College of Medicine.

Dr. Diamond has headed the rheumatology divisions at Albert Einstein School of Medicine and at Columbia University Medical Center. She also directed the Medical Scientist Training Program at Albert Einstein School of Medicine for many years. She is currently head of the Center for Autoimmune, Musculoskeletal and Hematopoietic Diseases at The Feinstein Institute for Medical Research and director of the PhD and MD/PhD programs at the Hofstra Northwell School of Medicine.

A former president of the American Association of Immunology, Dr. Diamond has also served on the board of directors of the American College of Rheumatology and the Scientific Council of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS).

Dr. Diamond is a fellow of the American Association for the Advancement of Science (AAAS) and a member of the Institute of Medicine.

Research Focus

There are many diseases characterized by the presence of autoantibodies, although the contribution of the autoreactive B cells and autoantibodies to tissue injury in these diseases is often unclear.

Dr. Diamond’s laboratory studies DNA-reactive B cells in the autoimmune disease systemic lupus erythematosus. Her team is interested in the alterations within B cells that lead to the survival and activation of DNA-reactive B cells and in the alterations in other cells of the immune system that affect B cell function and can also lead to the survival and activation of DNA-reactive B cells. They are also interested in the regulation of autoreactive B cells that acquire autoreactivity by somatic mutation during a germinal center response and in determining whether the processes that govern the selection of the B cell repertoire early in B cell development are the same as those that govern selection after activation. These studies are designed to provide new strategies to protect against autoimmune disease.

Dr. Diamond’s laboratory also examines whether autoantibodies in individuals with autoimmune disease or protective antibodies in non-autoimmune individuals might frequently cause brain injury if they penetrate the blood-brain barrier. It is their hypothesis that antibodies may frequently contribute to acquired changes in cognition or behavior.

Regulation of B cell repertoire

Dr. Diamond focuses on the regulation autoreactive B cells as they mature to immunocompetence and is particularly interested in the B cell receptor signaling pathway. It is her lab’s hypothesis that B cell hyperresponsiveness to antigen during early development allows autoreactive B cell to enter the native B cell repertoire. They have evidence that antigen mediates positive selection, as well as negative selection of transitional B cells, and are interested in delineating those conditions in which positive selection predominates and those conditions in which negative selection is triumphant.

The team is investigating the regulation of B cells that respond to antigen and acquire autoreactivity. They have shown that a process termed receptor editing causes post-germinal center B cells to express a new light chain in an effort to transform an autoreactive B cell receptor into one that is not autoreactive.

Hormonal effects on B cell development and selection

Most autoimmune diseases are more common in women and there is strong evidence that estrogen contributes to this female predisposition to autoimmune disease. Dr. Diamond is studying the impact of estrogen on B cell receptor signaling and B cell maturation to a marginal zone phenotype. She is further trying to understand if estrogen alters the germinal center response, as it has been shown to regulate both RAG and AID expression.

Dendritic cell regulation of B cell function

Dr. Diamond has been studying how alterations in function of dendritic cells can determine B cell selection and maturation. These studies provide information on an important link between the innate and the adaptive immune systems and will help identify new pathways for therapeutic intervention in autoimmune disease.

Antibodies and brain function

Dr. Diamond’s lab has become very interested in a subset of anti-DNA antibodies that cross-reacts with NMDA receptors and alters function in the adult brain following a breach in the blood-brain barrier and alters fetal brain development as a consequence of in utero exposure to maternal antibodies. They have recently extended their studies of anti-brain antibodies to ask whether these might account for some cases of autism and post-traumatic stress disorder.
