Learning outcomes
The basic aim of the course of General Pathology and Immunology are: (i) to acquire the conceptual and scientific tools to explain the causes and mechanisms of human disease and the role of the immune system; (ii) to examine molecular mechanisms responsible for cell and tissue damage and implicated in the host response to cell damage and in the repair of tissue injury. In addition, the course addresses pathophysiological mechanisms at the basis of alterations of the host main homeostatic systems, compensation responses induced by these alterations and their potential significance as mechanisms of diseases. Moreover, tumor eathiology, molecular mechanisms responsible of neoplastic transformation, development of primary tumors and metastasis, and the systemic consequences of tumor-related pathologies (paraneoplastic syndromes, chacexia) will be explored. Particular attention will be devoted to the acquisition of scientific terms used in pathology.

Organization of the immune system: 1. Anatomy of the immune syste: lymphoid organs in general (spleen, lymph nodes, Peyer patches, appendyx, bone marrow and thymus), lymphoid organs of the oral cavity (palatin, lingual and pharynx tonsils, district and intralingual lymph nodes, submucosal lymphatic cells, lymphatic tissue of salivary glands and of the gum) 2. Cytology of the immune system: lymphocytes, NK, dendritic cells. The lymphocytes classes: B and T lymphocytes and their subclasses. Antigens and antibodies. 3. Biochemistry of the immune system: molecules (Immunoglobulins, T cell receptor, MHC and costimulatory molecules). Physiology of the immune system: 1. Antigen processing and presentation. 2. The specific adaptive responses: cell mediated immune response and humoral. 3. Cyitokines and cell cooperation. 4. Defence against infections. 5. Defendive and offensive responses. 6. Active and passive immunoprophylaxis. 7. Immune tolerance. Pahology of the immune system: 1. Hypersensibility reactions. 2. Autoimmune diseases. 3. Immunodeficits. 4. Immunity and tumors. 5. Immuno-hematologya, blood groups. 6. Immunology of transplantation and HLA system. Immunology of the oral cavity: 1.Ecosistema e microbiologia del cavo orale. La placca batterica. Attivazione linfocitaria da parte di microrganismii a livello del cavo orale. 2. I meccanismi effettori umorali e le IgA secretorie. 3. Immunologia delle infezioni orali: carie, malattia parodontale, malattia pulpo-apicale, infezioni virali, micosi. Immunopathology of the oral cavity: 1. Systemic immune diseases and influences on the oro-pharynx; 2. The oral outcomes of hypersensibility and autoimmunity; 3. Consequences of the primary and secondary immune-deficiencies on the oral cavity, in particular HIV infections; 4. Immunology of dental transplantation.
