Therefore, the number of sequences obtained for CD161+ and CD161− Tconv from JIA PB was much lower compared to JIA SF, and the TCRβ repertoire of CD161+ and CD161− Treg from JIA PB was not analyzed due the small volumes of blood obtained from JIA patients and thus insufficient number of cells for sorting. This evidence concerns the gene KLRB1 and juvenile idiopathic arthritis.
