In contrast, therapeutic treatment of RSV-A2—infected ALI Calu-3 with either LL-37 or sLL-37 was associated with a reduction in the levels of RSV-A2 associated levels of expression of IP-10 (p = 0.035 and 0.038, respectively), but neither peptide significantly impacted the induction of RANTES expression in response to RSV-A2 infection. This evidence concerns the gene CCL5 and infection.
