Open Access Abstract Introduction Spondylarthropathies SpA are characterized by abnormal immune responses including T cell activation. Cytotoxic T lymphocyte associated molecule-4 CTLA-4 is involved in down-regulating immune responses. A soluble form of CTLA-4 sCTLA-4 resulting from an alternative splicing has been identified and was found increased in several autoimmune diseases. Here we evaluated circulating levels of sCTLA-4 as a marker of
