    The purpose of the investigation consisted in the study of morphological versions and activity of immunoselective markers in the epithelial component of the goitertransformed thyroid gland with the association of electron-microscopic changes and clinical manifestation of disease. As the primary antibodies were used mono- and polyclonal antibodies to the thyroid stimulating hormone (TSH), the vascular endothelial growth factor (VEGF) and the epidermal growth factor receptor (EGFR). It is established that the high expression of VEGF is observed in thyroid tissue, which loses sensitivity to the thyroid stimulating hormone, and vice versa. Hyperexpression of TSH, VEGF and EGFR in the nodular proliferating and adenomatous goiter indicates intensification of hyperplastic processes, the unbalance between clinical manifestation of disease and its biological potential of growth, which plays the key role in the determination of clinical prognosis of malignant potential of the nodular formation and postoperative relapse.

    Goiter

    Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...

    Hyperthyroidism II: Pathophysiology

    Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

    Synthesis and Regulation of Thyroid Hormones

    Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
    Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
    Graves Disease II: Pathophysiology01:24

    Graves Disease II: Pathophysiology

    Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
    The Thyroid Gland01:23

    The Thyroid Gland

    The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
    The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

    Functions of Thyroid Hormones

    The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
    TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
