Topics Covered

• Chaperonology: the study of molecular chaperones in all their aspects, normal and pathological. The chaperoning system: the entire complement of chaperones in an organism, including co-chaperones and co-factors. Chaperonopathies: diseases in which abnormal chaperones play a pathogenic role. Hsp60: the mitochondrial chaperonin Cpn60. Genetic Hsp60 chaperonopathies: pathologic conditions in which Hsp60 mutations are involved as etiologic-pathogenic factors. Hsp60 in cancer: Hsp60 chaperonopathies by mistake, in which the chaperonin helps the tumour rather than the patient
