Immunological Aspects of Preterm Birth: Phenotypes of Preterm Birth, Immune Mechanisms, and Pathway Forward bridges reproductive immunology of preterm birth to subtypes, phenotypes, and bedside prevention and treatment. The book reviews the role of the different immune mechanisms during pregnancy leading to preterm birth and fetal programming effects that are connected to maternal immune activation. The book also discusses immune cells and their products, cytokines and chemokines, as central for the success of the pregnancy, from the process of implantation to parturition and the effects of the changes on fetal programming. While our knowledge on the role of immune cells and the inflammatory process in preterm birth has grown exponentially in the last 10 years, connecting basic science to clinical science and development of new therapeutics has not progressed as rapidly. This book assists researchers in understanding the basic immunologic mechanisms and inflammatory processes associated with preterm birth and fills an urgent need for the development of therapeutics in this space.
