We did, however, demonstrate a dose-dependent decrease in IL-8 release and IL-8 mRNA induction in RSV-infected epithelial treated with the antioxidants dimethyl sulfoxide (DMSO) or 5,5-dimethyl-1-pyrroline-N-oxide (DMPO).
We observed elevated levels of Th2 cytokines (IL-3, IL-4, IL-10 and IL-13), pro-inflammatory cytokines and chemokines (IL-1β, IL-6, TNF-β, MCP-1/CCL2, MIP-1α/CCL3 and IL-8/CXCL8) in BALF from infants with RSV bronchiolitis, as compared to controls.
