Plasma Lipoproteins as Crucial Components of Host Defence Against Infections

Interactions between lipoproteins and infectious microorganisms are diverse and often multifaceted. There is a growing body of evidence which suggests that circulating plasma lipoproteins play an important role in warding off various infections. They are increasingly recognized as vital components of the host immune system. The purpose of this chapter is to provide the reader with an overview of this emerging domain. We review the anti-infective role of different lipoprotein particles and their components and further highlight the known molecular mechanisms involved therein. Instances where lipoproteins facilitate infections instead of protecting against them are also summarized. Finally, broad implications for the future in this active line of research are discussed
