Objective: T cell abnormal activation is thought to have a main role in the etiology of ankylosing spondylitis (AS). While cytotoxic T lymphocyte-associated molecule-4 (CTLA-4) is suppressing the immune system, in previous studies serum soluble CTLA-4 (sCTLA-4) was detected at high amounts in autoimmune disorders. We sought to evaluate the association between soluble CTLA-4 in serum and disease activity in AS patients.
