The article discusses the case of a 55 year old male with a history of seropositive rheumatoid arthritis refractory to treatment with methotrexate. He was included in the clinical trial of CTLA=4Ig plus MTX clinical trial. Significant clinical and serological responses were achieved during the treatment process. Since CTLA-4Ig has been used to block the interactions between CD80/CD86 on antigen presenting cells and CD28 on T lymphocytes, biological plausibility is possible.
