This detailed volume describes a series of techniques that are essential for evaluating the efficacy of new checkpoint blockade therapies as well as understanding the mechanisms behind the therapies that have already been approved. Beginning with a section on describing the tumor microenvironment and evaluating the immune system at a systemic level, the book continues by covering functional assays that provide answers to questions that may be raised after studying the immune system and its responses to immunotherapies, as well as the use of animal models in this research. 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. Authoritative and practical, Immune Checkpoint Blockade: Methods and Protocols serves to aid researchers in furthering our understanding of checkpoint blockage as well as the study of tumor immunology and the development of new immunotherapies.
