Abstract

The response to injury is dependent on several factors, including the type and extent of the injury, genetics, and the environment. In the present study, the genetic contribution to sepsis was evaluated in a mouse model. Sepsis was induced in two inbred mouse strains, C57BL/6J (B6) and A/J, by cecal ligation and single puncture (CLP). Frequency of mortality was significantly higher in B6 than A/J mice from 36 to 132 h after CLP. Plasma TNF-α, IL-1β, and IL-6 levels were similar in both strains after CLP. IL-10 plasma levels were significantly higher in B6 mice as opposed to A/J mice after 24 h of CLP. Similarly, hepatic myeloperoxidase activity, an index of polymorphonuclear leukocytes, was elevated in B6 mice as compared with A/J mice after 24 h of CLP. On the contrary, metallothionein mRNA levels were higher in A/J mice compared with B6 mice. Finally, leptin levels were also higher in A/J than B6 mice within 19 h of CLP. This study demonstrates a genetic contribution in the response to sepsis.
