abstract：:Delayed type hypersensitivity reaction (DTH) consists of a sequential cascade of steps depending on different types of T cells, as well as mast cells, endothelial cells and macrophages. Recently it has been shown that CD4+ TH1 lymphocytes ("inflammatory type") play a central role in DTH reaction. Activated TH1 cells p...
