T cell-dependent mast cell degranulation and release of serotonin in murine delayed-type hypersensitivity


We have previously suggested that the release of serotonin (5-hydroxytryptamine) (5-HT) by local tissue mast cells is required for the elicitation of delayed-type hypersensitivity (DTH) in mice. In the current study, light microscopic radioautographs from animals treated with [3H]5-HT indicated that local mast cells released 5-HT between 6 and 18 h during… (More)
