This book presents a comprehensive toolkit of versatile techniques for studying microglia under different experimental settings along with a brief summary of knowledge, accumulated in microglial research over the last decades. Beginning with recently discovered roles of microglia in health and disease, the volume continues by covering in vitro analyses of microglia, in vivo studies, and “omics” analyses. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
