Research Interest

Exploring the regulation of innate immune responses at mucosal tissues

Dr. Elia Tait Wojno investigates how innate immune responses are regulated during type 2 inflammation at mucosal barriers, which occurs in response to helminth infection and during allergic disease.  The Tait Wojno laboratory utilizes murine models of parasite infection and allergy and analysis of human and canine patient samples.  These studies focus on dissecting how cytokines, lipids, and cell-cell interactions shape the effector functions, development, and migration of rare immune cells including basophils and group 2 innate lymphoid cells.  Ultimately, the Tait Wojno laboratory seeks to unravel the cellular and molecular networks that regulate the activities of these cells at mucosal and barrier tissues such as the intestine, lung, and skin.  Current projects in the laboratory focus on 3 major areas:

  • The regulation of innate immune effector function in the intestine during helminth infection and in the lung during allergic inflammation. Ongoing studies focus on the role of prostaglandins in the lung and intestine in orchestrating type 2 inflammation via actions on various innate immune cells, employing cellular and molecular assays and genome-wide approaches.  These studies fill a gap in our understanding of how proteins, lipids, and cell-cell interactions via the Notch signaling pathway control innate immune cells that shape type 2 inflammation.
  • Cellular immune responses during canine allergic disease.  This study seeks to identify and characterize key immune responses that drive allergic inflammation in canine skin during atopic dermatitis.  This work addresses a major knowledge gap in canine immunology and will inform whether these key immune response are viable targets for the development of new treatments for canine allergy.  In addition, this work will help to establish naturally occurring allergic disease in companion dogs as a key model that can be used to learn more about atopy in general, benefiting both canine and human patients.
  • The development of the immune system.  Recent work in the laboratory focuses on how the cells of the immune system develop over a lifetime, with specific interest in the ontogeny of innate lymphoid cells and CD4+ T cells during health and disease.  These studies center around dissecting the factors that govern gene expression programs that specify immune cell lineages throughout the lifespan and downstream effects on functionality during infection.
