Induction of TNF-α and ECP release in human eosinophils by LPS and lipid A.
Eosinophils (2 × 106/mL) were stimulated with increasing concentrations of LPS (A and C) or lipid A (B and D) as indicated for 16 hours. TNF-α content in the culture supernatant was measured by ELISA (A and B). ECP concentration was determined in radioimmunoassay (C and D).
