RSV G protein inhibits cytokine and chemokine secretion, as infection with a recombinant RSV lacking the full-length G protein (rRSV-ΔG) or the soluble part of G protein (rRSV-ΔsG) enhances production of IL-6 and IL-8 in monocytes [95], and IL-8 and RANTES secretion, and ICAM expression in airway epithelial cells [96]. Here, IL6 is linked to infection.
