T cell History..??
Answers:
Human Treg Cells,,regulatory T lymphocytes (Treg cells) are recent discoveries in the greater than 50-year-old poke about for mechanisms of immunological tolerance to self. Although Treg cell were originally identified over ten years ago, they are still mortal characterized. The various types of regulatory T cell may not be mutually exclusive, and the interrelationships between them are not yet clearly defined. Induced regulatory T cell (eg. Th3 and Tr1) have also be described. Knowledge of the immunosuppressive mechanisms used by regulatory T cell may provide the basis for exotic clinical protocols to attenuate autoimmune disease and transplant rejection and to promote resistance to tumors and parasites.
As for who discovered them, I am not sure. But recent research from the laboratories of Barbara Fazekas DE St. Groth (Centenary Institute of Cancer Medicine and Cell Biology, Sydney, Australia) and Jeffrey Bluestone enjoy provided many piece to this puzzle.
