- PJ Maglione, MD, PhD is a physician-scientist in the Division of Clinical Immunology of the Department of Medicine. His research efforts in the areas of primary antibody deficiency and B cell biology have been supported by the Thrasher Research Fund, Clinical Immunology Society, and Jeffrey Modell Foundation. Dr. Maglione is board-certified by the American Board of Internal Medicine and the American Board of Allergy and Immunology, sees patients at the clinical immunology faculty practice, and supervises a weekly teaching clinic with the fellows in Mount Sinai's Allergy/Immunology training program.

Non-infectious complications of primary immunodeficiency
While susceptibility to infection is a hallmark of primary immunodeficiency, dysregulated immune function can occur, manifesting as autoimmunity, inflammatory disease, or malignancy. Dr. Maglione is exploring the clinical and immunological parameters that predispose certain patients to these non-infectious, but markedly deleterious, complications of primary immunodeficiency. He has a particular interest in studying interstitial lung disease and B cell lymphoproliferative complications occurring in common variable immunodeficiency, and is involved in clinical research studies exploring possible treatments. This work has the potential to elucidate the determinants of dysregulated B cell responses underlying many types of autoimmunity and maligancy.
T-independent antibody responses against bacteria
Current vaccines against bacteria are limited by serotype specificity and lack of long-term efficacy. With expanding resistance against antibiotics, new strategies for augmenting antibacterial immunity are clearly needed. Using a "bedside-to-bench" research approach, Dr. Maglione is studying human primary immunodeficiencies that impair the ability to produce antibodies against bacteria in order to understand the biological determinants of successful immunity against these pathogens. The goal of this work is to translate new information about how humans make antibodies against bacteria into novel strategies for immune therapies and vaccines. Particular attention is paid to "T-independent" antibody responses, as they are quite potent against bacteria but have not been extensively studied outside of animal models.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr. Maglione did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
