Immunity and Viral Infections

Immune Regulation

Under the direction of Woong-Kyung Suh

Research Unit

T cells play a central role in shaping the adaptive immune system. Against non-self antigens with pathogenic threat, T cells should develop immunity. On the other hand, T cells are supposed to become tolerant to self antigens or innocuous environmental antigens. Many immunological disorders such as immunodeficiency, autoimmune diseases, and allergies are caused by T cells that fail to obey the above rules.

Members of the CD28 family cosignaling receptors and their ligands (members of B7 family) are known to play crucial roles in T cell immunity and tolerance. The Immune Regulation Research Unit's team is investigating the molecular and cellular mechanisms of CD28-B7 family of T cell cosignaling molecules using a panel of knockout, knockin, and transgenic mice. Impacts of altered T cell cosignaling are analyzed at the biochemical and cellular levels using immune cells isolated from the mice. The consequences of altered cosignaling in overall immune reactions in mice are examined in the context of infection, cancer, and autoimmunity.
