TNF-α protein release. Secretion of TNF-α in (A) non-CF C38 cells and an isogenic CF IB3-1 cell line, (B) non-CF 16HBE14o- S1 cells and an isogenic CF 16HBE14o- AS3 cell line, and (C) 2CFSMEo- cells at a constitutive level and after treatment with AZM and JM. TNF-α protein levels were measured by a commercial enzyme-linked immunosorbent assay kit. The values represent the secretion levels relative to those of untreated (A) IB3-1, (B) 16HBE14o- AS3, and (C) 2CFSMEo- cells (means ± SD). The experiment was repeated three times. *, P < 0.05; **, P < 0.01.
