The determination of secreted levels of reactive oxygen species by implant-adherent cells in vivo is required for understanding of the role(s) of such reactive oxygen species for the tissue response around medical devices. A model with subcutaneous i

Hydrogen peroxide acts as electron acceptor in the oxidative reactions (iodination and coupling) by which the thyroid hormones are formed. Regulation of the generation of H2O2 was studied in monolayer cultures of the FRTL-5 rat thyroid cell line and

Locally produced proinflammatory cytokines are likely to play a pathophysiological role in autoimmune thyroid disease. An important feature of the thyroid, not previously considered in cytokine actions, is the barrier created by the follicular epithe

Protein iodination in the thyroid is largely confined to the surface of the epithelium. Intracellular iodine binding is insignificant. We have tested our hypothesis that the key mechanism in the control of intracellular iodination is the control of t

The transport of iodide was studied in porcine thyroid follicle cells cultured in bicameral chambers. The continuous layer of polarized follicle cells, joined by tight junctions, formed a diffusion barrier between the two compartments (apical and bas

In normal rats, the apical region of the thyroid follicle cells harbors a heterogeneous population of vesicular elements. Functionally, these are of at least two categories: endocytotic and exocy-totic. Elimination of TSH secretion, either by hypophy

The effect of monensin on the secretion of thyroglobulin was studied in open follicles isolated from pig thyroid tissue; in this system, thyroglobulin is secreted into the incubation medium. When monensin was present during a 4-h chase incubation aft

Generation of H2O2, an essential component in thyroid hormone synthesis, was studied by biochemical and cytochemical methods. Both parts of the study were performed on isolated open pig thyroid follicles in which the cells have preserved polarity and
