The Cytotoxic Ability of NK Cells in Children with Autoimmune Thyroiditis

Kucharska Anna , Popko Katarzyna , Osinska Iwona , Demkow Urszula

Background: In autoimmune thyroiditis type Hashimoto the key role in thyrocytes destruction plays the spontaneous cytotoxic activity of T cells, and antibodies dependent mechanisms are of a less value. A spontaneous cytotoxicity is associated with the number and degree of activity of NK cells. An important role in this process plays perforin contributed in permabilization of target cells.Objective and hypotheses: The aim of the study was to evaluate the ...

Background: The basic subset of T cells playing a major role in the pathogenesis of Hashimoto’s thyroiditis are CD8+T cells. The mechanism of disease initiation is dysfunction of natural Tregs leading to breakdown of the self-tolerance. The best known subset of natural Tregs are CD4+Foxp3+T, but CD8+T cells expressing CD122 were also recognized as functional Treg cells.Objective and hypotheses: The aimof the study was to evaluate the contribution of...
