AIMS AND CONTENT

LEARNING OUTCOMES

Molecular Oncology Cancer represents a special type of pathology that can be potentially dangerous even when affecting only an individual cell. At a molecular (biochemical-interactions) level, fundamental cellular functions (proliferation, apoptosis, differentiation, tissue architecture) are controlled by networks of signaling-proteins. Signaling-proteins networks decide when and in which way a cell will activate the above mentioned basic cellular functions. Special discrete sets of mutations / alterations, inheritable at the somatic level, from a parental to a daughter cell, can give origin to new progressively transformed cells, endowed with more permissive controls of these same functions. We want the student to learn the basic features of this pre-neoplastic and subsequently neoplastic transformation process. By about ten years, medicinal chemistry has started to discover selective inhibitors of altered signaling-proteins affected by excess of function (especially kinase inhibitors). We want the student to enter the world of possible selective corrections of altered pathways and altered signaling-network sub-regions. Molecular Immunology This course is aimed to provide a broad view of the current knowledge of the molecular mechanisms involved in the antigen-specific immune response and in innate immunity. Examples of translational applications of this basic knowledge to biotechnology approaches of therapy and diagnosis in neoplastic and immune-mediated diseases will be discussed.

AIMS AND LEARNING OUTCOMES

Knowledge of the molecular mechanisms responsible for the generation of neoplasia, complexity of the tumor microenvironment, clinical manifestations and features of the main neoplasia, ability to integrate the basic knowledge with the use of specific drugs that can interfere with the tumor cell growth and influence on the immune system. Knowledge of basic principle of the immune response in neoplastic, infectious, allergic and autoimmune diseases and of the up-to-date drugs used to modulate the immune response.

EXAM DESCRIPTION

Oral final examination

ASSESSMENT METHODS

Assessment will be carried out according to teaching calendar through an oral final exam (score out of thirty) that verifies the candidate's knowledge level. The evaluation of the final preparation will take into account the commitment shown during the all didactic activity period, the level of preparation, the use of proper language in relation to topics and presentation skills. Preparation will be valued at insufficient level if there will be gaps in one or more topics; the achievement of sufficiency will require a not fragmented knowledge of topics.
