NAC inhibits HA fragment-induced Gene expression in macrophages. ELISA for TNF-α and KC of cultured cell supernatants from MH-S (A, B) or PEC (C, D) cells stimulated with HA fragments (250 μg/ml) in the presence of NAC in concentrations as indicated at 37°C for 18 h. These data represent the average of 3 identical, independent experiments.
