The role of the E2F1 transcription factor in the innate immune response to systemic LPS.

ABSTRACT: Previous publications from our and other groups identified E2F1 as a transcription factor involved in the regulation of inflammatory response to Toll-like receptor ligands including LPS. In this study, we challenged E2F1-deficient mice with LPS systemically and demonstrated decreased survival despite attenuated inflammatory response compared with controls. Gene expression profiling of liver tissue identified a dampened transcriptional response in the coagulation cascade in B6;129(E2F1-/-) compared with B6x129 F2 mice. These data were further corroborated by increased prothrombin time, activated partial thromboplastin time, and fibrin split products in the blood of E2F1-deficient mice, suggesting disseminated intravascular coagulation as a consequence of uncontrolled sepsis providing at lea
