Outline of Final Research Achievements |
We evaluated the role of CRTH2 using a mice model of polymicrobial sepsis. CRTH2 knockout (-/-) mice were highly resistant to sepis and peritoneal bacterilal load in CRTH2-/- mice was significantly lower as compared to that in wild-type mice.Pharmacological inhibition of Gr-1, a neutrophil marker, and CXCR2 attenuated the protective effects aganist sepsis in CRTH2-/- mice, indicating that CXCR2-expressing neutrophils play protective roles in CRTH2-/- mice in this sepsis model. Moreover, acetylation of histone H3 at CXCR2 promoter in perippheral neutrophils was reduced 2 h after the surgery in wild-type neutrophils, while that in CRTH2-/- mice was not reduced 2 h after the surgery, suggesting that CXCR2 expression is regulated by epigenetic change.
