Outline of Final Research Achievements |
A tissue-penetrating homing peptide, CARSKNKDC (CAR) has previously demonstrated the unique ability to facilitate transport of co-administered drugs into injured endothelial cell. Co-administration of hydrocortisone and CAR could improve the endothelial disorder and survival in sepsis using lower amounts of hydrocortisone.Mice were given lipopolysaccharide (LPS, 20 mg/kg). Subsequently, five different treatments were initiated: saline only; CAR peptide-alone administration 500 ug; hydrocortisone 0.2mg/kg or 10mg/kg ; and CAR co-administered with hydrocortisone 0.2mg/kg. Hydrocortisone and /or CAR peptide were injected intraperitoneally at 3, 12 and 24 hours after LPS administration. Forty-eight hours after LPS administration, combined thrapy group showed the best survival ratio. These results suggest that co-administration of hydrocortisone and CAR peptide is a highly effective treatment strategy for endothelial disorder in sepsis.
