Figure 2From: Induction of IL-6 and CCL5 (RANTES) in human respiratory epithelial (A549) cells by clinical isolates of respiratory syncytial virus is strain specificInduction of IL-6 by clinical isolates NH1067 and NH1125. A549 cells were infected with multiplicity of infection (moi) 1 and IL-6 concentrations in cell culture supernatants were measured by ELISA. Ultraviolet light (UV) inactivated virus was used as a control. Standard error bars are displayed.Back to article page
