Contribution to Science

  • discovery that Tregs require iron for their proliferation post-birth and in cancer
  • description of Treg expansion in a genetic hypolipidemia
  • demonstration of a glycolytic-lipogenic circuit governing Treg expansion in cancer
  • observation that type I interferons can modulate Treg dynamics in autoimmunity
  • description of CD8 T cells specific to apoptosis-associated antigens in chronic viral infections and autoimmunity
  • study of OX40 in effector Treg expansion in human cancers
  • characterization of OX40 in Treg function, expansion, and interaction with mast cells
