Research

submenu

Research within the Center for Immunology focuses on several key aspects of immunity.

Tolerance and autoimmunity

  • How does the immune system acquire tolerance to self-proteins?
  • How are self-reactive T and B lymphocytes eliminated during development?
  • What are the biochemical mechanisms by which T cell tolerance is maintained in the peripheral immune system?
  • Why does the immune system have so much difficulty recognizing tumor cells as foreign?
  • How do the various cells in the immune system collaborate to maintain tolerance to self proteins?
  • What are the consequences of a breakdown in immunological tolerance?
  • What is the molecular basis of autoimmune diseases?

Lymphocyte activation

  • How does the immune system respond to antigenic peptides?
  • How does immunological memory develop?
  • What are the biochemical signaling pathways that initiate and regulate T and B cell activation?
  • How are T cells maintained in the body in a state of readiness?
  • What is the molecular basis for the antibody response?
  • What are the mechanisms that regulate the movement of leukocytes through the body?
  • How do T cells regulate the function of other T cells?

Lymphocyte development

  • How are T and B lymphocytes educated during development to distinguish between self and non-self?
  • What are the environmental cues that regulate lymphocyte development?
  • What are the biochemical pathways that regulate T and B cell development?
  • How do undifferentiated stem cells develop into hematopoietic cells?

Transplantation

  • What is the immunological basis of transplant rejection?
  • How can our knowledge of the immune system be used to enhance the survival of transplants?
  • What are the mechanisms of rejection in xenotransplantation?

Faculty researchers
Blazar, Fife, Kyba, Miller, Tolar

Tumor immunotherapy

  • Can we use our understanding of how the immune system functions to develop new and more effective immunotherapies?

Faculty researchers
Fife, Jameson, Kaufman, Mescher, Miller, Pennell

Immune response to infection

  • How is the host immune response to pathogens regulated?
  • What are the cellular and cytokine signals required for protective immunity against infection?
  • What are the unique features for activating pathogen-responses at mucosal infection sites?
  • How can we optimize vaccination for protective immunity?
