C57BL/6 mice were pretreated with recombinant（r） VIP, while BALB/c mice were pretreated with VIP antagonist, and then infected with A. fumigatus. Clinical score was recorded. Expression of pro-and anti-inflammatory cytokines, toll-like receptor 4（TLR4）, lectin-like oxidized low-density lipoprotein receptor 1（LOX-1）, and neutrophil infiltration were tested by PCR, enzyme-linked immunosorbent assay（ELISA）, and myeloperoxidase（MPO） assay.RESULTS： VIP mR NA expression in BALB/c cornea was higher than C57BL/6 cornea at 1 and 3 d post infection（p.i.）. rV IP treatment of C57BL/6 mice showed alleviated disease and down-regulated expression of interleukin-1β（IL-1β） and tumor necrosis factor-α（TNF-α）, while IL-10 expression was up-regulated. Neutrophil infiltration and TLR4, IL-17 expression were decreased after rVIP treatment, while LOX-1 expression was up-regulated in C57BL/6. VIP antagonist pretreatment showed increased disease and higher IL-1β, TNF-α, TLR4, IL-17 and MPO levels, while IL-10 and LOX-1 levels were down-regulated in BALB/c mice.CONCLUSION： rVIP alleviate disease response of C57BL/6 mice. VIP antagonist resulted in worsened disease of BALB/c mice. VIP proposed anti-inflammatory role in A. fumigatus keratitis.展开更多
