However no similar data concerning this thyroid-specific gene expression in patients with AITD have been published so far; our results seem to be in line with the findings of Caillou et al. [17], who demonstrated that in the subjects with lymphocytic thyroiditis follicular cells distant from lymphocytic infiltrates were negative or exhibited weak NIS immunostaining. The gene discussed is SLC5A5; the disease is Hashimoto thyroiditis.
