About Stephen Canfield

Dr. Stephen Canfield is a board certified Allergist/Immunologist and member of the American Academy of Allergy, Asthma, and Immunology. He is an Assistant Professor of Medicine at CUMC in the division of Pulmonary, Allergy, and Critical Care Medicine.

Dr. Canfield earned his PhD in Immunology and Microbiology at Columbia University and went on to earn his MD there as well. He completed residency training in Internal Medicine at New York Presbyterian Hospital, where he served as Chief Medical Resident. He subsequently completed clinical training in Allergy and Immunology at Columbia University and has been practicing since 2001. In addition to clinical practice, Dr. Canfield serves as the Associate Program Director for the Allergy/Immunology clinical training program, and directs the Immunology Section of the major preclinical medical student course. He also serves as a curriculum advisor to medical schools in Southern Africa and in the Dominican Republic.

Dr. Canfield completed his doctoral training in the area of immunoglobulin structure and effector function with Dr. Sherie Morrison at UCLA. Following an internal medicine residency, he transitioned into T cell biology, studying the mechanisms by which activated T cells adhere to extracellular matrix (ECM) in a post-doctoral fellowship with Dr. Seth Lederman at the Columbia University College of Physicians and Surgeons. These studies led to the discovery that a receptor for laminin previously associated only with tumor metastasis mediates laminin adherence in activated CD4+ T lymphocytes.

Dr. Canfield went on to pursue clinical training in the field of Allergy/Immunology at Columbia with Dr. Paul Rothman, during which time he developed a murine model recapitulating the genetic predisposition to asthma associated with single nucleotide polymorphisms in the human IL-4 receptor alpha chain. These studies led to the discovery of a novel IL-4 signaling pathway mediated by members of the MAP kinase signaling family.

The murine model of IL-4 receptor SNP effects remains one of the ongoing research endeavors in Dr. Canfield's lab. In the past two years, the lab's interests have moved in a translational direction with two projects directly examining the response of human peripheral blood T cells to a variety of antigen stimuli in vitro. One project, examining the effects of environmental tobacco smoke (ETS) on the development of allergies and asthma, focuses on a sample of children recruited from NYC neighborhoods with high rates of asthma and allergy. Current studies aim to characterize the T cell proliferative and cytokine response to these allergens among sensitized and non-sensitized individuals, and to identify effects of ETS exposure on the T cell allergen-specific response. In a second translational study, Dr. Canfield has joined a collaborative effort with Drs. Chess and Jiang examining mechanisms of peripheral immune regulation. Previous work by Drs. Jiang and Chess in a murine model of autoimmunity identified a population of CD8+ T lymphocytes capable of suppressing autoreactive CD4+ effector T cells and preventing emergence of autoimmune disease. Evidence from this model regarding the mechanism by which CD4+ T cells are targeted for suppression suggests that this regulatory process may be important in the avoidance of a variety of "inappropriate" immune responses, including autoimmune and allergic responses in humans. The aim of these collaborative studies is to apply the evidence gathered in the mouse system to characterize the orthologous regulatory system in humans. Among the disease conditions under study are type 1 diabetes mellitus, allergic rhinitis, and asthma.

In summary, Dr. Canfield's research interests involve both basic and translational approaches toward an overarching aim of elucidating the mechanisms underlying the maladaptive T cell immune responses that precipitate allergy and autoimmunity.

Research Interests

  • Characterization of molecular signaling events following interleukin-4 stimulation of B, T Cells
  • Molecular mechanism by which gene encoding the IL-4Ra are associated with asthma and atopic disease
