摘要

Inflammatory infiltrates in tissue-specific autoimmune disease com- prise a collection of T cells with specificity for an antigen in the target organ. These specific cells recruit a population of non- specific T cells and macrophages. The rare tissue-specific T cells in the infiltrate have the capacity to regulate both the influx and the efflux of cells from the tissue. Administration of an altered pep- tide ligand for the specific T cell which triggers autoimmunity can lead to the regression of the entire inflammatory en- semble in a few hours. Interleukin 4 is a critical cytokine involved in the regres- sion of the inflammatory infiltrate.
