The phosphoinositide-3 kinase survival signaling mechanism in sepsis

Shock. 2010 Nov;34(5):442-9. doi: 10.1097/SHK.0b013e3181e14ea9.

Abstract

Phosphoinositide-3 kinases (PI3Ks) are critical regulatory proteins in the immunologic defense system against sepsis. The PI3K mechanism helps modulate cellular survival, innate and adaptive immunities, inflammation, nuclear factor-κB transcription, and may, in turn, play a protective role in sepsis. Animal studies confirm its role in the prevention of organ dysfunction and improvement of survival outcomes. Further advances in the understanding of this key immunomodulatory pathway may provide valuable insights into the manipulation of cellular function for therapeutic treatment of sepsis and other inflammatory diseases.
