The Role of Phosphoinositide 3-Kinase Signaling in Intestinal Inflammation

Abstract EN

The phosphatidylinositol 3-kinase signaling pathway plays a central role in regulating the host inflammatory response.

The net effect can either be pro- or anti-inflammatory depending on the system and cellular context studied.

This paper focuses on phosphatidylinositol 3-kinase signaling in innate and adaptive immune cells of the intestinal mucosa.

The role of phosphatidylinositol 3-kinase signaling in mouse models of inflammatory bowel disease is also discussed.

With the development of new isoform specific inhibitors, we are beginning to understand the specific role of this complex pathway, in particular the role of the γ isoform in intestinal inflammation.

Continued research on this complex pathway will enhance our understanding of its role and provide rationale for the design of new approaches to intervention in chronic inflammatory conditions such as inflammatory bowel disease.
