IL-8 is a major neutrophil chemoattractant (Baggiolini et al., 1989; Bazzoni et al., 1991), and neutrophils are implicated in the development of exaggerated RSV-associated lung disease in children and infants (Everard et al., 1994; McNamara et al., 2003; Emboriadou et al., 2007; Sebina and Phipps, 2020). Here, CXCL8 is linked to lung disorder.
