Immunomodulation by vasoactive intestinal peptide is associated with increased survival and growth of Salmonella Typhimurium in mice

摘要

Studies have shown that administration of vasoactive intestinal peptide (VIP) in mice rescues them from lethal endotoxaemia and that this is correlated with decreased concentration of inflammatory cytokines. VIP has, therefore, been proposed as a novel anti-inflammatory which could be used in the treatment of Gram negative sepsis. However, the effect of VIP has not been reported in mice infected with viable Gram negative bacteria.
