The subject matter of this chapter is defined by the title of its two previous editions, "Immunohistochemistry of human Hsp60 in health and disease: From autoimmunity to cancer," the latest of which appeared in 2018. Since then, considerable advances have been made in the fields of autoimmunity and cancer and some of them are closely linked to progress in the understanding of the chaperone system (CS). This is a physiological system composed of molecular chaperones, co-chaperones, chaperone cofactors, and chaperone interactors and receptors. The molecular chaperones are the chief members of the CS, and here we focus on one of them, Hsp60. Since extracellular vesicles (EVs) have also emerged as key factors in the functioning of the CS and in carcinogenesis, we have incorporated a detailed section about them. This chapter explains how to assess Hsp60 in tissues and in EVs for application in diagnosis, prognostication, and patient monitoring and, eventually, for developing methods using them as therapeutic targets and tools. We describe immunohistochemical techniques, immunofluorescence and double immunofluorescence-confocal microscopy, and methods for collecting and isolating EVs from blood plasma and for assessing their contents in Hsp60 and related microRNAs (miRNAs). All these procedures have proven to be reliable and useful in the study and management of various types of cancer and inflammatory and autoimmune conditions. © 2023.
