Our therapies are based upon our unique understanding of T cells and the central role they play in immunity



T cells are at the heart of most immune responses. We have focused our research efforts on two classes of T cells: T effector cells and T regulatory cells.

T effector cells direct the immune response that destroys cancer cells, cells infected by viruses and bacteria, and—in the case of autoimmune disorders—our own tissues

T regulatory cells modulate the appropriate activation and inhibition of T effector cells, prevent the immune system from attacking normal cells and tissues, and—in cancer—inappropriately protect malignant cells

Inappropriate activation or inhibition of T cells plays a central role in type 1 diabetes mellitus (T1DM) and other autoimmune diseases and cancer.

  • T1DM and other autoimmune diseases occur when inappropriately activated T effector cells attack normal cells and tissues, including:
  • Beta cells of the pancreas
  • Skin cells
  • Nerve tissue
  • Joint tissue

  • In cancer, T regulatory cells may prevent the development of a robust immune response that can attack and destroy cancer cells

Tolerx is a world leader in understanding the relationship between T effector and T regulatory cells and in developing immunotherapeutics that can safely and effectively manipulate that relationship in order to achieve a desired therapeutic effect.

  • In T1DM and other autoimmune diseases, Tolerx immunotherapeutics are designed to:
  • Downregulate inappropriately activated T effector cells to stop ongoing autoimmune attack
  • Upregulate T regulatory cells to protect against future attacks
  • In cancer, Tolerx immunotherapeutics are designed to:
  • Upregulate tumor-antigen-specific T effector cells that direct the attack against a tumor
  • Enable these T effector cells to resist the effects of T regulatory cells that are inappropriately inhibiting them from attacking the tumor


Additionally, we are developing surrogate markers and prognostic indicators of T regulatory cell function, which may possibly serve as early indicators in clinical studies.
