The role of osteopontin in inflammatory processes

TLDR
Besides its function in inflammation, OPN is also a regulator of biomineralization and a potent inhibitor of vascular calcification.
Abstract
Osteopontin (OPN) is a matricellular protein that mediates diverse biological functions. OPN is involved in normal physiological processes and is implicated in the pathogenesis of a variety of disease states, including atherosclerosis, glomerulonephritis, cancer, and several chronic inflammatory diseases. Through interactions with several integrins, OPN mediates cell migration, adhesion, and survival in many cell types. OPN also functions as a Th1 cytokine, promotes cell-mediated immune responses, and plays a role in chronic inflammatory and autoimmune diseases. Besides its function in inflammation, OPN is also a regulator of biomineralization and a potent inhibitor of vascular calcification.

The multiple functions and mechanisms of osteopontin.

TL;DR: The aim of the present review is to address majority of different functions of OPN protein which are known, suspected or suggested through the data obtained about this protein yet.

CD44 variants but not CD44s cooperate with _1-containing′ integrins′ to permit cells to osteopontin independently of arginine-′ glycine-aspartic acid, thereby stimulating cell motility and′ chemotaxis.

TL;DR: In this article, the authors show that osteopontin (OPN), CD44, and integrins cooperate to enhance cell motility and promote cell spreading, motility, and chemotactic behavior.
