Influence of tumor necrosis factor (TNF) on levels of human neutrophil peptides 1-3 (HNP1-3) of mixed synoviocytes. The data are derived from five OA and five RA patients (two replicates of every patient). Control HNP1-3 levels were 58.3 ± 7.0 pg/ml in OA patients and 147.2 ± 37.5 pg/ml in RA patients.
