This book includes current research in the life cycle, functions and diseases associated with macrophages. Topics discussed include macrophages as regulatory and effector cells in the immune system; macrophages from human pluripotent stem cells; mucosal macrophage phenotype and functionality in homoeostasis and pathology; macrophage plasticity and polarization;...
