CONTENTS OF THYROID HORMONES, CYTOKINES AND α2-MACROGLOBULIN IN BLOOD SERA AND IN CULTURE SUPERNATES OF BLOOD CELLS FROM THE GRAVES DISEASE PATIENTS
We had investigated levels of TTG, T4, TNFα, IL-6, IFNγ, and α2-MG in blood serum and supernates of short-term blood cultures in the patients with verified Graves disease before treatment and after reaching of euthyroid status, as compared with healthy controls. We have revealed that initial blood c...

| Sumario: | We had investigated levels of TTG, T4, TNFα, IL-6, IFNγ, and α2-MG in blood serum and supernates of short-term blood cultures in the patients with verified Graves disease before treatment and after reaching of euthyroid status, as compared with healthy controls. We have revealed that initial blood concentrations of free Т4 in the patients were increased, along with decrease in TSH, higher IL-6, IFNγ levels, as well as concentrations of α2-MG which participates in cytokine transport and synthesis. Thiamazole treatment normalized the hormonal profile and reduced blood levels of IL-6, IFNγ and α2-MG, however, without complete normalization, along with increase of serum TNFα contents. It was shown, that the patients before treatment had decreased in vitro response of cells to the mitogenic stimulation as shown by decreased induction of TNFα and IFNγ production, along with, increased spontaneous IFNγ levels. When reaching euthyroid state after Thiamazole administration, we observed an increased spontaneous IFNγ synthesis, decreased IL-6 production in resting cultures. In mitogen-stimulated cell cultures from the treated patients, IFNγ contents became normal, however, TNFα secretion remained lower than in controls. The α2-MG levels in supernates were stable and significantly lower, than in serum. We may presume that thyrotoxicosis treatment with Thiamazole causes stabilization of the endocrine state, however, being not sufficient for normalized production of cytokines, as well as α2-MG, with its regulatory and transporter functions, thus promoting recurrence of disease and reactivation of autoimmune events. |
