Dr. Ashira Blazer joined HSS in 2022 as an Assistant Attending Physician and Assistant Professor of Medicine at Weil Cornell Medical College. She received her medical degree from Baylor College of Medicine and completed her residency at Vanderbilt University Medical Center. She went on to complete rheumatology fellowship and a masters of science at NYU School of Medicine, where she trained in the laboratories of Drs. Jill Buyon and Timothy Niewold.
Dr. Blazer specializes in the treatment of all rheumatic diseases including undifferentiated connective tissue disease, Sjogren’s syndrome, inflammatory arthritis, and systemic lupus erythematous (SLE), particularly in patients of African ancestry. Considered a prototypic autoimmune disorder, SLE represents a phenotypically heterogeneous syndrome with multiple genetic, environmental, and immunologic causes. As a physician scientist, Dr. Blazer studies the interplay between genetic polymorphisms commonly found in African ancestry backgrounds, environmental and social stressors, and SLE pathogenesis. With increased prevalence of kidney, cardiovascular disease, and hypertension, SLE patients of African ancestry often experience higher disease severity and accelerated damage accrual. Dr. Blazer's work aims to understand contributing factors, and gain insights into personalized treatment options for this most vulnerable group of patients.
Dr. Blazer's primary area of focus is in studying two cytokine-responsive genetic variants of apolipoprotein L1 (APOL1) gene, which have been linked to both atherosclerosis and renal disease in African ancestry populations. In SLE, chronic inflammation may be an important amplifying factor increasing the consequence of carrying one or more APOL1 variant. Her early work has identified that SLE patients who carry these variants have an increased risk of hypertension, cardiovascular disease, chronic kidney disease, and overall organ damage accrual. In a truly translational approach, Dr. Blazer has utilized cell culture techniques to understand how SLE-relevant immune mediators, such as interferons, increase APOL1 expression and precipitate cytotoxicity. She has recently received grant funding to study the specific immune pathways that induce APOL1 gene expression in SLE. She ultimately aims to identify potential ways to repurpose targeted biologic therapy to both impact SLE disease activity and genetic risk in APOL1 variant carriers.
Dr. Blazer is widely seen as an area expert in SLE, and has been recognized by the National Minority Quality Forum as a Top 40 under 40 leader in minority health. She is a thought leader in SLE disparities and has served in leadership roles for the American College of Rheumatology, Lupus Foundation of America, Lupus Research Alliance, Association of Women in Rheumatology, African League of Associations for Rheumatology, and Lupus Nephritis Trials Network Among others.

Dr. Blazer's current translational research project focuses on polymorphisms in the Apolipoprotein L1 (APOL1) gene, which are exceptionally common in those of West African heritage as they confer protection against African trypanosomiasis. APOL1, a major contributor to excess renal and cardiovascular risk in the African diaspora, is responsive to inflammatory cytokines and may be of heightened consequence in chronic inflammatory disease sufferers such as SLE patients. She is interested in integrative computational methods for elucidating immune regulation of APOL1, and the resultant risk phenotypes in SLE. Ultimately she aims to identify accessible biomarkers of APOL1 associated disease in SLE patients, and contributory interacting factors which can be targeted to improve therapies.
Work in both of these areas is designed to identify key mechanisms of disease affecting patients of African ancestry which may be targeted to improve clinical outcomes. Dr. Blazer has spearheaded unique African ancestry biorepositories, including in collaboration with rheumatologists in Accra, Ghana, and Lagos Nigeria, that continue to generate patient samples and clinical data. With the goal of becoming a leader in lupus throughout the African diaspora, these cohorts create the foundation for her academic career in understanding SLE in African ancestry patients.
