Learning outcomes of the course unit
In depth knowledge of the etio-pathogenetic factors that underlie the alterations of structures and functions involved in human disease at molecular, cellular, and whole-organism levels. In depth knowledge of the mechanisms involved in the response to tissue injury at different levels of integration.
Course contents summary
Introductory concepts. Health and homeostasis. Deviations from homeostasis. The etiology of tissue injury at molecular level. Extrinsic causes of disease: Physical causes; Chemical causes; Biological causes. Intrinsic causes of disease: Single-gene disorders with classic and non classic inheritance; Multifactorial diseases; Cytogenetic disorders
Cellular pathology. Reversibile and irreversibile cell injury. Adaptive mechanisms to cell injury: hypertrophy, hyperplasia, atrophy, metaplasia, dysplasia. The ischemic-hypoxic stress: Mechanisms; Metabolic consequences; Reperfusion injury; Cell death: necrosis and apoptosis
