HLA-B and uveitis: First, we compared the gene expression of 29 ocular CD8+ T cells with the HLA-B*27 axSpA motif in B27AAU to 1,535 expanded ocular CD8+ T cells from other forms of uveitis (non-B27AAU) (Figure 2A and Supplemental Figure 1), identifying 76 upregulated DEGs in ocular CD8+ T cells with the HLA-B*27 axSpA motif (Figure 2B).
