title: Role of activated T lymphocytes in mycosis fungoides.
abstract: A patient with mycosis fungoides was treated effectively with the immunosuppressant cyclosporine A. Excretion of urinary neopterin, a marker of activation of the cellular immune system, fell immediately at the start of therapy. This result argues in support of a central role of activated T lymphocytes in this disease as has already been proposed by other authors.
