Data presented as the percentage mean ± standard deviation. The differences for all percentages between patients with ankylosing spondylitis (ASp) and either HLA-B27-negative healthy donors (HD1) or HLA-B27-positive healthy donors (HD2) were significant (P < 0.001, according to a two-tailed significant level of 0.05). There were no significant differences between HD1 and HD2 (P > 0.05). Th, CD4⁺ T-helper cells; T, T lymphocytes; L, lymphocytes; Treg, forkhead box P3-positive regulatory T cells.
