Autoinduction of tumor necrosis factor-in FRTL-5 rat thyroid cells

Tumor necrosis factor(TNF ) may play a role in the development of autoimmune thyroiditis such as Hashimoto’s thyroiditis. In the present study, we examined whether TNF induced its own expression in FRTL-5 rat thyroid cells. Lipopolysaccharide (LPS) markedly increased TNF mRNA levels in FRTL-5 cells as assessed by semiquantitative RT-PCR. In addition… (More)
