Expression levels of CD160 on CD4⁺ T and CD8⁺ T cells in AS patients. Blood samples were collected to detect CD160 expression levels on both CD3⁺CD8⁺ and CD3⁺CD8⁻ (most CD4⁺) T cells by flow cytometry. a Representative dot plots and histograms of CD160 expression on CD3⁺CD8⁻ (most CD4⁺) and CD3⁺CD8⁺ T cells from HC (upper panels) and AS patients (bottom panels). b The percentages of circulating CD160⁺CD3⁺CD8⁻ T cells (upper graph) and CD160⁺CD3⁺CD8⁺ T cells (bottom graph) in HC and AS patients with each dot representing one subject. Data are expressed as mean ± SD. Student t test (b).
