title: Plasma selectin levels in patients with Graves' disease.
abstract: Adhesion molecules relate to cell invasion of autoimmune thyroid disease. We studied plasma soluble P-Selectin (platelet activation-dependent granule-external membrane protein), E-Selectin (endothelial leukocyte adhesion molecule) and L-Selectin (leukocyte endothelial cell adhesion molecule-1) levels in patients with Graves' disease before and during methimazole treatment. Plasma P-, E- and L-Selectin levels in patients with untreated Graves' disease were significantly higher than those in normal subjects. Plasma P-Selectin levels decreased when their thyroid functions were normal for more than 6 months after the start of methimazole treatment. No significant change in plasma E- and L-Selectin levels in patients with Graves' disease was found between hyperthyroid state and euthyroid state after the start of methimazole treatment, but plasma L-Selectin levels in patients with untreated Graves' disease were significantly lower than those in the patients in the first euthyroid state. There was no significant correlation between plasma P-Selectin levels and serum FT4 levels, nor between plasma P-Selectin levels and serum FT3 levels. These results suggested that thyroid hormones might reflect expression of P-, L- and E-Selectin from endothelial cells, or lymphocytes, or platelets in patients with Graves' disease.
