title: Suppressor cell activity in progressive systemic sclerosis.
abstract: Prostaglandin-producing suppressor cell activity was significantly increased in patients with progressive systemic sclerosis (p less than .01). No significant differences were found in concanavalin-A induced suppressor T cell activity. Although these results indicate an alteration in immunoregulatory function they may represent a compensatory reaction to a defect in the regulation of fibrogenesis.
