An increase of the overall T-lymphocytes, CD4−CD8− T-lymphocytes, and CD8+T-lymphocytes was observed in the ir thyroiditis samples compared to the healthy thyroid samples (61.3% vs. 20.1%, p = 0.00006; 1.9% vs. 0.7%, p = 0.006; 38.6% vs. 25.7%; p = 0.0259, respectively). Here, CD8A is linked to thyroiditis.
