The Company's CD6 plays a central role in the modulation of effector T cell, or Teff cell, activity and trafficking. Activated Teff cells drive several immuno-inflammatory diseases across therapeutic areas including transplant science, systemic autoimmunity, pulmonary, neurologic, gastrointestinal, renal, vascular, ophthalmic and dermatologic disorders.
