The exact pathogenesis of silent thyroiditis is not fully understood. It is thought that silent thyroiditis is the result of an [[autoimmune]] phenomenon. Activated matured T-cells ([[HLA-DR|HLA-DR+]]CD3+), activated [[Helper T cells|helper/inducer T-cells]] ([[HLA-DR|HLA-DR+]]CD4+), activated [[Suppressor T cells|suppressor]], and [[Cytotoxic T cell|cytotoxic T-cells]] ([[HLA-DR|HLA-DR+]]CD8+) were higher in patients with silent thyroiditis as compared to the healthy controls. It indicates that the activation of T cells, especially [[Helper T cells|helper/inducer T cells]], might have an important role in the [[pathogenesis]] of silent thyroiditis. Silent thyroiditis is associated with the [[HLA DR3-DQ2|HLA-DR3]] and [[HLA-DR5|DR5]] genes. [[Lymphocytic]] infiltration of the thyroid gland, the absence of Hurthle cells and [[Germinal center|germinal centers]] on histological analysis are the microscopic [[histopathological]] findings suggestive of silent thyroiditis.

* [[TSH]] acts on [[thyroid gland]] by binding to specific membrane receptors and activating an [[intracellular]] pathway involving [[cAMP]] that ends in the formation and secretion of [[thyroid hormones]].
* [[Iodine]] is essential for the synthesis of [[thyroid hormones]]. [[Iodide]] is taken up through a special Na/I transporter found in the membrane of [[thyroid]] follicular cell. After the [[iodide]] uptake, it goes through a series of organic reactions ending in the formation of the two forms of [[thyroid hormones]]: [[T3]] and [[T4]]. [[T3]] and [[T4]] remain stored in the [[thyroglobulin]] within thyroid follicles and are released in response to further stimulation by [[TSH]] to the [[Thyroid follicle|thyroid follicles]].

* While [[T3]] is 3 to 5 times more potent than [[T4]], it represents only one-fourth of the total hormone secretion. [[T3]] is thought to be the biologically active form of the hormone. Most of the circulating [[T3]] is due to peripheral conversion of [[T4]] in the liver and peripheral tissues while only a small percentage is secreted directly from the [[thyroid gland]] itself.

Overview

The exact pathogenesis of silent thyroiditis is not fully understood. It is thought that silent thyroiditis is the result of an autoimmune phenomenon. Activated matured T-cells (HLA-DR+CD3+), activated helper/inducer T-cells (HLA-DR+CD4+), activated suppressor, and cytotoxic T-cells (HLA-DR+CD8+) were higher in patients with silent thyroiditis as compared to the healthy controls. It indicates that the activation of T cells, especially helper/inducer T cells, might have an important role in the pathogenesis of silent thyroiditis. Silent thyroiditis is associated with the HLA-DR3 and DR5 genes. Lymphocytic infiltration of the thyroid gland, the absence of Hurthle cells and germinal centers on histological analysis are the microscopic histopathological findings suggestive of silent thyroiditis.

Pathophysiology

The control, synthesis, and release of the thyroid hormone is usually controlled by hypothalamus and pituitary gland.[1][2]
