This second edition focuses on various techniques to investigate aspects of the TNF Superfamily members in health and disease. Chapters detail protocols on the signaling process of TNF family members, technical examples to investigating the role of TNF family members in physiopathologies, modulation of TNF signaling by pathogens, experimental applications of TNF-reporter mice, methodologies for various assays of TNF family members and the production of recombinant molecules. Written in the highly successful series format, 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 accessible, serves to aid researchers investigating this key family of proteins.
