  It has been proved that TRAM-derived decoy peptides have anti-inflammatory properties.In this study,we synthesized a TRAM-derived decoy peptide (TM6), belongs to TRAM TIR domain, of which sequence is "N"-RQIKIWFQNRRMKWK, KENFLRDTWCNFQFY-"C" and evaluated the effects of TM6 on lipopolysaccharide-induced mastitis in mice.In vivo, LPS-induced mice mastitis model was established by injection of LPS through the duct of mammary gland.TM6 was injected 1 h before or after LPS treatment.In vitro, primary mouse mammary epithelial cells were used to investigate the effects of TM6 on LPS-induced inflammatory responses.The results showed that TM6 inhibited LPS-induced mammary gland histopathologic changes, MPO activity, and TNF-α, IL-1β and IL-6 production in mice.In vitro, TM6 significantly inhibited LPS-induced TNF-α and IL-6 production,as well as NF-κB and MAPKs activation.In conclusion, this study demonstrated that TM6 had protective effects on LPS-mastitis and may be a promising therapeutic reagent for mastitis treatment.
