Comparison Of Intravenous Versus Intraperitoneal Interleukin-10 Gene Delivery In Mouse Model Of Sepsis

Abstract

The most novel approach utilizing IL-10 in sepsis is IL-10 gene delivery in experimental model of sepsis. In our study, we aimed to compare kinetics of intravenous versus intraperitoneal delivery of IL-10 gene transfer in early stages of sepsis. This is a prospective controlled experimental study. Six groups were gathered with 20 Swiss-Albino female mice. Intra-abdominal sepsis was induced by cecal ligation and puncture (CLP). Animals had either intraperitoneal or intravenous IL-10 liposomal gene transfer. Animals were sacrified 24 h after injections, followed by harvest of lung, liver, spleen, vena cava tissues. Immunostaining revealed more prominent staining in liver after intraperitoneal delivery. All endothelial tissues stained with intravenous delivery. There was striking difference between tissue expressions of transgene of animals in CLP intravenous group when compared to other groups. Our results point out that pro-inflammatory action of IL-10 is prominent in intravenous gene delivery which shows itself with induction of zyon. IL-10 still may harbor therapeutical potential which still needs to be explored.
