Abstract
New opportunities are opening up in the study of the relationship between the antigenic structure of thyroid autoantigens and autoantibodies in the pathogenesis of such autoimmune diseases as Graves’ disease (GD) and autoimmune thyroiditis (AIT) using synthesized recombinant proteins of the thyroid-stimulating hormone receptor (TSHR) and human thyroid peroxidase (TPO). In the present work, the results of cloning of the fragments of the TPO extracellular domain and fragments of the RNA sequence of the α-subunit of TSHR, which do not contain nucleotide substitutions, are demonstrated. Recombinant vectors for the expression of proteins of the α-subunit of thyroid-stimulating hormone receptor and fragments of the TPO extracellular domain have been obtained.
