The induction of tolerance with CD154 Ab and donor-specific transfusion was not possible when allogeneic skin was transplanted onto mast-cell deficient mice. Moreover, the investigators provided evidence linking the production of IL-9 by Tregs to mast cell accumulation and allograft tolerance (86). If mast cells are found in the lymph node tissue, it means the tumor has spread and additional treatment is needed. Additional Treatment Options for Mast Cell Tumors in Dogs. A mast cell is a type of white blood cell. (86) found that the presence of mast cells was essential for Treg-dependent allograft tolerance.

Mast cell: A granulocyte found in connective tissue whose normal function is unknown but that is frequently injured during allergic reactions. A mast cell is a white blood cell which contains granules. Phenotypically, the granules of most synovial mast cells contain both tryptase and chymase (MC TC), though mast cells staining for tryptase alone (MC T) are also observed in varying proportion, usually in mast cells found close to the synovial lining.
