Summary of cytokines and chemokines produced during RSV infection

Cytokine	Source	Effects
IFN-γ	NK cells, CD4+ T cells, CD8+ T cells	Increases NK activation, Th1 differentiation
IL-1β	Macrophages	Increases expression of cytokines mediated by NF-κB
IL-4	CD4+ T cells	Increases Th2 differentiation, decreases Th1 differentiation
IL-8	Epithelial cells, Macrophages	Neutrophil recruitment
IL-10	CD4+ T cells	Inhibits expression of inflammatory cytokines, suppresses inflammatory response
IL-17A	CD4+ T cells	Increases Th17 differentiation, increases inflammatory cytokine production
