Production of migration inhibitory factor in response to bacterial and fungal antigens in patients with untreated Graves' disease.
Tests for the production of migration inhibitory factor by peripheral blood leukocytes in response to ubiquitous bacterial and fungal antigens were carried out in patients with untreated Graves' disease and in healthy control subjects. Dose-response studies, tests for the production of this factor after 72 hours' stimulation with phytohemagglutinin as a test for reserve, and tests before and after 24 hours' preculture to deplete suppressor cells were also performed in some patients. The antigens used were Candida, Trichophyton-Oidiomyces-Epidermophyton, mumps live attenuated virus and purified protein derivative of tuberculin. The production of migration inhibitory factor was measured by the agarose microdroplet method.The production of migration inhibitory factor in response to all the antigens except mumps virus was slightly greater in the patients than in the control subjects, although the differences were not significant. The dose-response characteristics and the production of migration inhibitory factor after stimulation with phytohemagglutinin were similar in the two groups. The production of migration inhibitory factor in response to suboptimal concentrations of Candida, Trichophyton-Oidiomyces-Epidermophyton and mumps virus was not enhanced in either group after 24 hours' preculture apart from a slight increase in response to mumps virus in the patients.These results fail to support the suggestion that patients with Graves' disease have a deficiency of suppressor cells.
