Adelstein's research focuses on clinical immunology and allergy, encompassing immune tolerance mechanisms, B and T cell function, primary immunodeficiencies, autoantibodies, autoimmune diseases such as systemic sclerosis-associated interstitial lung disease, myositis-associated interstitial lung disease, pemphigus vulgaris, and neuromyelitis optica spectrum disorder, as well as inflammasome activation, biomarkers, and anaphylaxis. His highly cited publications include 'Altered immunoglobulin expression and functional silencing of self-reactive B lymphocytes in transgenic mice' (Nature, 1988; 2074 citations), 'Interleukin-2 receptor γ chain mutation results in X-linked severe combined immunodeficiency in humans' (Cell, 1993; 1671 citations), 'Induction of self-tolerance in T cells but not B cells of transgenic mice expressing little self antigen' (Science, 1991), and more recent works such as 'A Composite Serum Biomarker Index for the Diagnosis of Systemic Sclerosis–Associated Interstitial Lung Disease' (Arthritis & Rheumatology, 2023). With over 8500 citations on Google Scholar, his contributions have advanced understanding of immune dysregulation and diagnostic approaches in autoimmune and allergic conditions.
